Physics trigger group rates at the High-Level Trigger (HLT) as a function of time in a fill taken in September 2018 with a peak luminosity of L = 2.0 x 1034 cm-2s-1 and a peak average number of interactions per crossing of <μ> = 56. Presented are the rates of the individual trigger groups specific to trigger physics objects. Each of the groups contains single-object and multi-object triggers. Overlap between groups is only accounted for in the total main physics stream rate. The B-physics and Light States (LS) triggers are mainly muon-based trigger algorithms; the majority of the triggers are written to the B-physics and LS stream and are thus not included here. The combined group represents multiple triggers of different objects, as combinations of electrons, muons, taus, jets and missing transverse energy. Common features to all rates are their exponential decay with decreasing luminosity during an LHC fill. The rates periodically increase due to a change of prescales to optimise the bandwidth usage or LHC luminosity re-optimisations; dips are due to dead-time and spikes are caused by detector noise.

Trigger stream rates as a function of time in a fill taken in September 2018 with a peak luminosity of L = 2.0 x 1034 cm-2s-1 and a peak average number of interactions per crossing of <μ>=56. Presented are the main physics stream rate, containing all triggers for physics analyses; the B-physics and light states (LS) stream, containing triggers specific to B-physics analyses; the express stream, which records events at a low rate for data quality monitoring; other minor streams with physics applications, such as zero-bias and background events; the trigger-level analysis (TLA) stream; the detector monitoring streams; and the detector calibration streams. The increase of the TLA HLT output rate is part of the end-of-fill strategy of the ATLAS trigger. At the end of the LHC fill, level-1 and CPU resources are available to reconstruct and record additional events using lower-threshold TLA triggers. The TLA stream only selects events containing jets and saves the HLT jets and limited event information, leading to a much smaller event size than in regular data-taking. This increases the total HLT output rate, but does not significantly increase the total output bandwidth due to the small size of TLA events.

Output bandwidth at the HLT as a function of time in a fill taken in September 2018 with a peak luminosity of L = 2.0 x 1034 cm-2s-1 and a peak average number of interactions per crossing of <μ>=56. Presented are the main physics stream rate, containing all triggers for physics analyses; the B-physics and light states (LS) stream, containing triggers specific to B-physics analyses; the express stream, which records events at a low rate for data quality monitoring; other minor streams with physics applications, such as zero-bias and background events; the trigger-level analysis (TLA) stream; and the detector calibration streams. The monitoring stream is not reflected in the output bandwidth as the monitoring data are not written out to disk. The increase of the trigger-level analysis (TLA) HLT output is part of the end-of-fill strategy of the ATLAS trigger. At the end of the LHC fill, level-1 and CPU resources are available to reconstruct and record additional events using lower-threshold TLA triggers.

Presented are rates of some representative single-object trigger items, which have not been prescaled. These trigger items are based on such objects as electromagnetic clusters (EM), muon candidates (MU), jet candidates (J), missing transverse energy (XE) and tau candidates (TAU). The number in the trigger name denotes the trigger threshold in GeV. The letters following the threshold values refer to details of the selection: variable thresholds (V), hadronic isolation (H), and electromagnetic isolation (I). Common features to all rates are their exponential decay with decreasing luminosity during an LHC fill. The rates increase periodically due to LHC luminosity re-optimisations; dips are due to dead-time and spikes are caused by detector noise.

Trigger rates and bandwidth for trigger-level analysis

Total level-1 (L1) trigger output rate as a function of instantaneous luminosity in a typical fill taken in September 2018. Also shown are the rates of the individual trigger items seeding the Trigger-Level Analysis (TLA) stream, without accounting for overlaps between the individual items. The letter “J” followed by number in the trigger name denotes a jet satisfying a given energy threshold in GeV. The suffix “DETA20-J50J” denotes a leading jet with ET > 50 GeV, separated from the sub-leading jet by η < 2.0. The TLA stream only selects events containing jets and saves the HLT jets and limited event information, leading to a much smaller event size than in regular data-taking. The increase of the L1 rate is part of the end-of-fill strategy of the ATLAS trigger. At the end of the LHC fill, L1 and CPU resources are available to reconstruct and record additional events using lower-threshold TLA triggers and so the prescales of these triggers are reduced or removed at certain luminosity points, as shown by the increases in rate at L = 1.2, 1.0, and 0.7 x 1034 cm-2s-1. This increases the total HLT output rate, but does not significantly affect the total output bandwidth due to the small size of TLA events. Other periodic rate increases are due to a change of prescales on other triggers (not shown) to optimise the bandwidth usage or LHC luminosity re-optimisations; dips are due to dead-time and spikes are caused by detector noise.

Output bandwidth of the High Level Trigger (HLT) as a function of time in an LHC fill taken in May 2018 with a peak luminosity of L = 1.76*1034 cm-2s-1 and a mean number of interactions per crossing peaking at 54. Presented are the total HLT output bandwidth for all trigger streams (solid line) and only that for the Trigger Level Analysis (TLA) stream (dashed line). The total HLT output bandwidth includes data from all ATLAS trigger streams, including the TLA stream and the main physics stream which selects events that contain all physics objects and full detector information. The TLA stream only selects events containing jets and saves the HLT jets and limited event information, leading to a much smaller event size than in regular data-taking. The exponential decay is due to the decreasing luminosity during an LHC fill, while dips are due to deadtime. The increase of the TLA output bandwidth is part of the end-of-fill strategy of the ATLAS trigger. At the end of the LHC fill, L1 and CPU resources are available to reconstruct and record additional events using lower-threshold TLA triggers. This increases the total HLT output rate, but does not affect the total output bandwidth significantly due to the small event size of TLA events. This first occurs when the instantaneous luminosity has dropped to L = 1.2*1034 cm-2s-1 (at 21:50), when these triggers are activated with a prescale of 12, and then a larger increase occurs at L = 1.0*1034 cm-2s-1 (at 23:50) when the prescale is removed.

The trigger rate is shown for the Level-1 trigger L1_MJJ-500-NFF as a function of the instantaneous luminosity for LHC fill 7139, taken in September 2018. The trigger is implemented in the Level-1 topological trigger where two lists sorted by the jet pT are formed, and each list can contain up to six entries. The first list includes all jets that have pT > 30 GeV and |η| < 3.1 while the second list includes all jets with pT > 20 GeV. The dijet mass MJJ is computed using one jet from each list and events with MJJ > 500 GeV pass the trigger requirement.

Trigger Rates and bandwidth

Internal link: ATL-COM-DAQ-2017-076

Physics trigger group rates at the High Level Trigger (HLT) as a function of time in a fill taken in June 2017 with a peak luminosity of L = 1.53 * 1034 cm-2s-1 and a peak pile up of mu = 43. Presented are the rates of the individual trigger groups specific to trigger physics objects. Each of the groups contain single and multi triggers of the same object. Overlaps are only accounted for in the total Main Physics Stream rate. The B-physics and Light States (LS) triggers are mainly muon-based trigger algorithms; the majority of the triggers are written to the B-physics and LS stream and are thus not included here. The combined group represents multiple triggers of different objects, as combinations of electrons, muons, taus, jets and missing transverse energy. Common features to all rates are their exponential decay with decreasing luminosity during an LHC fill. The rates periodically increase due to change of prescales to optimise the bandwidth usage or LHC luminosity re-optimisations, dips are due to deadtime and spikes are caused by detector noise.

L1 Trigger Rate

Total Level 1 (L1) rate as a function of time throughout a fill taken in October 2016 with a peak luminosity of L = 1.31* 1034 cm-2s-1 and a peak pile up of μ= 42. At the start of the run the rate is artificially increased to a maximum of 97kHz by adding additional L1 total energy triggers. Subsequently the additional rate is removed and the rate follows an exponential decay with decreasing luminosity during an LHC fill. There are periodically increases due to changes of trigger prescales to optimise the output bandwidth usage and dips due to temporary detector deadtime at that specific moment of data taking.

L1Topo Commissioning

Level 1 rates before prescale versus instantaneous luminosity for L1 di-tau chains. All chains require two isolated hadronic taus with ET > 20,12 GeV. ‘L1_TAU20IM_2TAU12IM_J25_2J20_3J12’ requires the presence of an additional jet with ET >25 GeV based on an object counting performed at CTP. In the ‘DR’ chains, the topological cut ΔR < 2.9 between the two taus is applied by the L1Topo hardware. In ‘DR-TAU20ITAU12I-J25’, the presence of a jet with ET >25 GeV and not overlapping in ΔR < 1 with the two taus is also required at L1Topo. Data have been collected in pp collisions at a center-of-mass energy of 13 TeV in 2016.

Efficiency of the L1Topo selection as function of the ΔR(τ,τ) between offline tau candidates in di-tau events. The selection implemented at L1 by the L1Topo hardware requires two isolated taus with ET > 20,12 GeV and ΔR < 2.9. The efficiency is computed in data events collected in 2016 and selected by a di-tau trigger with the same energy and isolation selections, but no ΔR cut. The L1Topo selection is fully efficient for di-tau events reconstructed offline with ΔR(τ,τ) < 2.5.

Plot of invariant mass distribution for pairs of oppositely charged offline reconstructed muons, shown for events passing a nominal HLT trigger chain (triangles) and the equivalent HLT chain with additional L1Topo requirements (circles). The offline muon pairs are fit to a common vertex, using the inner detector track parameters. The two triggers chains each require two muons at L1, passing thresholds of pT > 6 GeV, which are confirmed at the HLT, with oppositely charged muons fit to a common vertex, using the inner detector track parameters, and with invariant mass requirements made to restrict events to the b-hadron invariant mass range. L1Topo makes additional requirements that L1 muons form an invariant mass between 2 and 9 GeV, and have opening angle between 0.2 and 1.5. The rate reduction at L1 achieved by L1Topo by approximately a factor of four, results in a reduction of efficiency of approximately 12% at the HLT due to the selection requirements and the difference in resolution of muon direction reconstruction at L1 and HLT.

Using a background data sample collected by calorimeter-based triggers, we calculate efficiency turn-on curves for two L1Topo triggers based on the HT algorithm as a function of the offline-reconstructed HT, the transverse energy sum of jets. HT150_J20_ETA31 (HT190_J15_ETA21) requires the transverse energy sum of jets with pT > 20 (15) GeV and pseudo-rapidity |eta| < 3.1 (2.1) to be above 150 (190) GeV. The full L1Calo stream of run 298595 is used. Events triggered by calorimeter-based triggers (not including topological triggers) are sent to this stream and contain information about the decision of topological triggers. The efficiency of these triggers with respect to the full sample of events is shown as a function of the offline reconstructed HT calculated using the appropriate selection of reconstructed jets.

The fixed frequency veto of the innermost pixel detector of ATLAS (IBL) protecting against irreparable damage due to resonant vibration of the wire bonds has a direct impact on the maximal tolerable rate at the first trigger level (L1). This limit depends on the number of colliding bunches in ATLAS and on the filling scheme of the LHC beams. This plot presents the simulated rate limits of the L1 trigger from the IBL for two different filling schemes and the expected maximal L1 rate from rate predictions. The steps in the latter indicate a change in the prescale strategy. The simulated rate limit is confirmed with experimental tests. The rate limitation was only critical for the lower luminosity phase, where the required physics L1 rate was higher than the limit imposed by the IBL veto. Tighter prescales were then used.

The ATLAS trigger system records complete information from online trigger processing with each accepted event. This information is then copied to Analysis Object Data (AOD) format which is created by offline reconstruction algorithms. In the new ATLAS analysis model adopted in 2015, AOD payload is reduced using analysis specific filters that keep minimum information necessary for each type of analysis. This filters include reduction in trigger payload by keeping only information necessary for matching particle candidates selected by a given analysis with particle candidates selected by the online trigger system. This reduction in the trigger payload is achieved using a navigation framework which associates selected trigger candidates with logical trigger requirements. This plot shows a typical size reduction in percent of the trigger navigation payload size for specific representative filters used by physics analyses. In each case information related to a broad range of triggers is saved.

HLT algorithms execution caching

This plot illustrates effects of Region of Interest (RoI) based execution caching mechanism for trigger algorithms executing at the second level trigger (L2) of the ATLAS trigger. The caching mechanism reuses results from earlier executions of the same algorithm which is shared by other triggers present in trigger configuration. This caching works in the context of the same RoI and it records inputs and outputs of each algorithm execution.

This plot illustrates effects of Region of Interest (RoI) based execution caching mechanism for trigger algorithms executing at the second level trigger (L2) of the ATLAS trigger. The caching mechanism reuses results from earlier executions of the same algorithm which is shared by other triggers present in trigger configuration. This caching works in the context of the same RoI and it records inputs and outputs of each algorithm execution.

This stream contains events that were selected using special triggers which accept the main L1 physics triggers without further HLT selection. These special triggers were then disabled for the offline HLT tests resulting in HLT rejection comparable to that obtained in typical physics data taking.

Level-1 rates for the forward-jet triggers up to 7.3x10^33 cm-2 s-1. The 2FJ15 is a trigger for two forward jets (|η|>3.2) with a 15 GeV threshold (one such object is called FJ15); EM14VH_FJ15 is a two-object trigger for an electron or a photon above 14 GeV and an FJ15 item; 3J15_FJ15 is a four-object trigger for three central jets (|η|<3.2) with a 15 GeV threshold and a FJ15; 2TAU8_TAU11I_EM10VH_FJ15 is effectively a three-object trigger for an isolated hadronically decaying tau lepton above 11 GeV, an electron or a photon above 10 GeV, and a FJ15; MU10_FJ15 is for a muon trigger with two-station coincidence above 10 GeV and an FJ15 item. The forward jets are very susceptible to pile-up effects. This is mitigated by the use of energy threshold requirements that are adjusted for a peak pile-up scenario that corresponds approximately to a luminosity of 5x10^33 cm-2 s-1. This leads to a change in the behavior of the triggers above that luminosity. The jet thresholds are quoted at the electromagnetic scale, so the response to hadronic energy is lower. The jet thresholds at 15 GeV are efficient for offline jets with ET above 50 GeV; the tau at 11 GeV are efficient above 40 GeV.

Level-1 Trigger cross-sections (rate/luminosity) for a selection of L1Calo-based trigger items. The left side of the figure corresponds to measurements from two 7TeV runs with 2011 nominal per-bunch luminosities, and colliding bunches delivered in bunch trains with 50ns spacing. The right side of the figure corresponds to a special high-luminosity 7TeV run with no bunch trains. The middle of the figure corresponds to an 8TeV run with 2012 nominal per-bunch luminosities and 50ns bunch trains. The falls in rate for XE50 and FJ75 triggers between 2011 and 2012 runs are due to trigger noise-cut increases in the forward regions of L1Calo. All other rate changes (increases) are due to the increased centre-of-mass energy. EM16 (EM30) is an electron-photon trigger with a threshold at 16 (30) GeV.

EM16VH is an electron-photon trigger with an hadronic layer energy veto and varied thresholds across the calorimeter, with typically 16 GeV thresholds. TAU15 is an hadronically-decaying tau trigger with threshold at 15 GeV. XE50 is a trigger for missing ET above 50 GeV at the EM scale. XE50_BGRP7 is an XE50 trigger with a veto on the first 3 bunches of a bunch train. J75 is a trigger for a central jet (|η|<3.2) with ET above 75 GeV. FJ75 is a trigger for a jet in the forward region (|η|>3.2) with ET above 75GeV. 4J10 is a trigger for four central jets with ET above 10GeV.

The left side of the figure corresponds to measurements from two 7TeV runs with 2011 nominal per-bunch luminosities, and colliding bunches delivered in bunch trains with 50ns spacing. The right side of the figure corresponds to a special high-luminosity 7TeV run with no bunch trains. The middle of the figure corresponds to an 8TeV run with 2012 nominal per-bunch luminosities and 50ns bunch trains. The falls in rate for MU4, MU10 and MU11 triggers in the left of the figure are due to a reoptimization of the associated trigger co-incidence windows. The fall in rate for MU10, MU11, MU15 and MU20 between 2011 and 2012 are due to further co-incidence window reoptimizations, and additional shielding installed in the region between the experiment’s barrel and endcap regions. Other trigger rate changes (increases) are due to the change in centre-of-mass energy. Rate decreases in the special high luminosity run are due to the long gap between colliding bunches.

MU0-MU10 are triggers for muons with pT above the indicated thresholds (in GeV). MU0 uses a full-open loosest coincidence, MU4-MU10 require co-incident hits in at least two RPC stations, or three TGC stations. MU11-MU20 require co-incident hits in all three stations of the trigger system in all regions. 2MU4 (2MU6) is a trigger for two muons with pT above 4 (6) GeV.

Trigger rates per bunch crossing, relative to the rate in bunch crossing ID 141, measured across one of the bunch trains of a typical 50ns-spacing LHC fill. L1_XE25 is a missing transverse energy trigger. L1_EM30 is a single electron/photon trigger requiring ET threshold of 30GeV. L1_MU10 is a single muon trigger with pT threshold of 10GeV. The L1_XE25 trigger has a significantly higher rate near the start of bunch trains due to the unbalanced overlaying of bipolar calorimeter signal shapes from neighbouring bunches. The lower rate in the first bunch for L1_MU10 is due to a contribution to rate in later bunches from delayed hits in the muon trigger chambers. .png

LHC bunch timing measured in ATLAS BPTX

Beam phase during spring 2010-summer 2011
The time difference between the LHC bunch arrival time and the LHC RF clock during spring 2010-summer 2011. The bunch arrival times are measured by the beam timing pick-ups (BPTX) for beam 1 and beam 2. The phase includes an arbitrary offset to tune the phase to zero for a particular reference point. A fine-delay of 2ns was applied to the clock on 25 June and 6 July 2010 in order to shift the beam phase closer to zero. From July 2010 the beam phase is being kept constant within +/- 500 ps. To adjust the timing signals with an even higher precision (10ps) a new module (CORDE) was installed during the shutdown in 2010.

LHC clock drift during spring 2010-summer 2011
The time difference between the LHC bunch arrival time and the LHC RF clock during spring 2010-summer 2011. The bunch arrival times are measured by the beam timing pick-ups (BPTX) for beam 1 and beam 2. The phase includes an arbitrary offset to tune the phase to zero for a particular reference point. The beam phase shown in this graph excludes a clock fine-delay that was applied in hardware in order to correct for long-term time drifts. The open circles show a direct propagation delay measurement of an optical signal through spare clock fibers that cover a fraction of the full 13.3 km long clock fiber distance between the RF (Point 4) and Point 1. An appropriate scale factor and shift has been applied to match the curve with the beam phase measurements. The good agreement within 300ps indicates that the long-term drift of the beam phase is due to a drift of the propagation delay in the optical fiber.

Deadtime of different trigger items
This plot shows the Level-1 deadtime fractions for the trigger items L1_MU10, L1_EM14 and L1_TE180 for a long run on 5th June 2011. The deadtime fraction is the ratio of events which were triggered but vetoed to all triggered events. The spikes are due to a DAQ /sub-detector veto. The difference of the deadtime fractions can be explained by a bunch crossing dependent trigger response (see next plot).

Bunch crossing dependent trigger response
This plot shows the Trigger After Prescale (TAP) rates for the trigger items L1_MU10, L1_EM14 and L1_TE180 in a bunch train. The rates are scaled so that they fit well on one plot. It can be seen that L1_TE180 fires much more often for the first two bunches in a train than for the rest (due to LAr pulse shape). The first two bunches in a train see a low Simple deadtime and for this reason the overall deadtime of L1_TE180 is decreased. The variation of the L1_EM14 rate can be explained by the varying luminosity of the bunch crossings. The increased L1_MU10 rate for the second bunch can be explained by late muon triggers. The vetoing of late muon triggers due to the Simple deadtime enhances the overall L1_MU10 deadtime

Bunch crossing dependent deadtime
The left part of the plot shows the contributions of Simple and Sub-detector/DAQ deadtime to the total deadtime fraction for different bunches in a train. The right part of the plot shows the distribution of the deadtime fractions for all bunch crossings. The three peak structure originates in the Simple deadtime: The first bunch in a train sees no Simple deadtime, the second bunch sees the Simple deadtime of the first bunch. Following bunches in a train see the deadtime of the previous two bunches.

The time is broken down into CPU time needed to run the algorithm and the time to retrieve region-of-interest data over the LVL2 network. The aim of this plot is purely to illustrate the capabilities of the HLT to collect detailed monitoring of times information. Times are per event.

Example of LVL2 trigger prescale changes during a run.
Here the L2_vtxbeamspot_activeTE_peb trigger (an arbitrary choice to illustrate the point) is initially disabled for the ‘warm start’ period, then enabled at luminosity block (LB) 255 when LHC stable beams are declared. As the beam intensity falls, the input rate drops by almost a factor of 4. The prescale factor is reduced, without restarting the run, in a few steps to keep the output rate between about 6 to 12 Hz. A LB is a time interval (~1 min) during which luminosity and conditions are considered to be approximately constant, and the smallest unit of data that can be declared good or bad for physics analysis. Prescale changes are therefore made on LB boundaries. (Internal note: run 153565.)

Unprescaled L1 rates as a function of the instantaneous luminosity for a trigger requiring a single hit in one of the minimum bias trigger scintillators mounted on each side of the experiment (MBTS_1). Each dot represents a measurement in a time interval of about two minutes in runs taken in June and July 2010 with two (nb=2, red), respectively four (nb=4, blue) colliding bunches. The measurement of the inst. luminosity is already corrected for pile-up effects. As expected, the MBTS rates saturate due to pile-up as they approach two times, respectively four times the LHC revolution frequency, i.e. at nb*fLHC~22 kHz and nb*fLHC~44 kHz. L1RateMBTS.png

In addition, the rate of interactions (IA, grey) after unfolding the pile-up contribution is shown featuring a nicely linear behavior. This demonstrates the stability of the MBTS trigger with respect to the luminosity detector LUCID.

L1 muon trigger rates as a function of luminosity
Measured L1 trigger rates as a function of the instantaneous luminosity for different L1 thresholds. The rates are fitted with a function taking into account the luminosity and filling scheme dependent part of the trigger rate. The steps are due to different filling schemes changing the contribution of cosmic radiation to the trigger rate.

LHC bunch timing measured in ATLAS BPTX

Bunch timing measured by the ATLAS beam pick-up detectors on March 30, 2010
The difference in time of arrival of bunch number 1 is shown in green. The time difference is constant at around 40ps +/- 20ps (RMS). The individual bunch timing, the time of arrival of bunch number 1 with respect to the LHC 40 MHz clock, is shown in blue/red respectively for beam 1 and 2. An expected shift of -200ps is observed during the acceleration period from 0.45 to 3.5 TeV.

Beam phase during spring/summer 2010
The time difference between the LHC bunch arrival time and the LHC RF clock during spring/summer 2010. The bunch arrival times are measured by the beam timing pick-ups (BPTX) for beam 1 and beam 2. The phase includes an arbitrary offset to tune the phase to zero for a particular reference point. A fine-delay of 2ns was applied to the clock on 25 June and 6 July 2010 in order to shift the beam phase closer to zero. From July 2010 the beam phase is being kept constant within +/- 500 ps.

LHC clock drift during spring/summer 2010
The time difference between the LHC bunch arrival time and the LHC RF clock. The bunch arrival times are measured by the beam timing pick-ups (BPTX) for beam 1 and beam 2. The phase includes an arbitrary offset to tune the phase to zero for a particular reference point. The beam phase shown in this graph excludes a clock fine-delay that was applied in hardware in order to correct for long-term time drifts. The open circles show a direct propagation delay measurement of an optical signal through spare clock fibers that cover a fraction of the full 13.3 km long clock fiber distance between the RF (Point 4) and Point 1. An appropriate scale factor and shift has been applied to match the curve with the beam phase measurements. The good agreement within 300ps indicates that the long-term drift of the beam phase is due to a drift of the propagation delay in the optical fiber.

BPTX oscilloscope pictures

Scope traces of the beam pickup system (BPTX) from 23 November 2009, just before the phase adjustment of the LHC RF team. The beam 1 signal is shown in blue/turquoise, beam 2 in red. The green signal is the 25-ns clock. The phase difference between the two beams in ATLAS is the peak-to-peak time difference, 900 ps. This corresponds to a vertex shift in z of 13.5 cm.

Scope traces of the beam pickup system (BPTX) from 23 November 2009, just after the phase adjustment of the LHC RF team. Again the beam 1 signal is shown in blue/turquoise, beam 2 in red. The green signal is the 25-ns clock. The effect of the cogging can be clearly seen, the peaks lie on top of each other, beams are crossing at the center of ATLAS. The mean track z0 position was consistently found to have moved as well in the z direction, by 12 cm, as expected (see here).

2009 Data

Data taking efficiency

Data taking efficiency December 2009
The Data Taking Efficiency defined as the ratio of the running time during beam time to beam time is shown. The running time incorporates the dead time fraction during each Luminosity Block reported by the Central Trigger Processor. The beam time is defined by the presence of two circulating beams independent of their stability condition. Each data point corresponds to an average efficiency calculated for a period of 1 hour and a negative value indicates a period of no beam. Reasons for lower efficiency are stop of the run during beam time to work on a subsystem, unexpected arrival of the beam and possible trigger holds due to a sub-system issuing busy for a brief period of time.

Trigger Rates

MBTS and total rate
Figure shows the online monitored L1 rates as a function of time for three primary MBTS triggers used during collisions: MBTS_1 (black circles), MBTS_2 (red circles), MBTS_1_1 (green triangles). There are 16 scintillators on each side covering a rapidity interval of 2.09 < |eta| < 3.84. MBTS_1 requires one hit in any of the 2x16 scintillators, MBTS_2 requires 2 hits and MBTS_1_1 requires at least 1 hit in each side. The total EF rate to disk storage is also shown. The trigger rates are observed to correlate with the LHC beam intensities that were recorded during the same period.

L1 and HLT trigger rates for a typical run with stable beam flag. Also shown are a collision trigger at L1, requiring hits on both the A and the C side of the minimum bias scintillator counters and filled bunches for both beams. The line labled L2 Inner Detector activity represents a filtering algorithm at the L2 trigger, which accepts events based on space point counts in the Inner Detector. This L2 algorithm receives 5% of all filled bunches as input from L1. Assuming both the L1 collision trigger and the space point counting are highly efficient for collision events, the difference in the two lines should reflect this fraction, even though the acceptance of both triggers is different. The moment the L2 algorithm is enabled is clearly visible as the jump of output L1 rate, and the start of event rate on the L2 line. The dips in HLT and L1 output rates just before this moment are due to the short pause needed to change trigger setup. The HLT output rate (which represents the rate of events recorded to disc) does not visibly change, as it is dominated by a constant rate of monitor triggers. The slide-jpg file contains some explanations added to the picture.

L1 rates for run 141811
Figure shows the average online monitored L1 trigger rates for all triggers that had an average rate in excess of 0.1 Hz, demonstrating that a number of trigger are firing at the L1 trigger with some rate, exercising the trigger system. Note the absolute values are as monitored online, and have not been corrected for beam setup or instant luminosity, and will therefore differ from run to run.

L1 rates for run 141811
Figure shows the average online monitored L2 trigger rates for all triggers that had an average rate in excess of 0.1 Hz, demonstrating that a number of triggers are firing at the high level trigger with some rate, exercising the trigger system. Note the absolute values are as monitored online, and have not been corrected for beam setup or instant luminosity, and will therefore differ from run to run.
