Contact the Trigger coordinator or the TDMT in case of questions and/or suggestions.

## L1 Trigger

### L1 Muon Barrel (RPC)

 This plot is only for Trigger Sector 39. It shows the mean value of the distribution of track Theta passing by a given PAD+CM-eta (y-axis), versus the ordinal number that indentifies the PAD and its CM-eta (from PAD=0, CM=0 : bin 0; to PAD=6, CM=3, bin 13). No CM-phi are considered, because at the moment the trigger is configured differently for them; and because two CM-phi in the same PAD are at the same $\theta$ angle wrt the beam axis. The plot clearly provides an example of the different behaviour of the L1_MU6 and L1_MU10 thresholds from the L1_MU0 threshold: the former do grow approx. linearly with the angle Theta of the PAD+CM-eta, in order to have the track always pointing to the I.P., whereas the latter is essentially flat, with a slight structure from the shaft sculpting. Plots obtained on full statistics from run 131227, looking at the CosmicMuons stream. Contact: Giuseppe Salamanna

### L1 Muon End Caps (TGC)

 TGC_LVL1 : trigger timing distribution with single-beam is shown. The unit of X-axis is Bunch-Crossing, it means 25nsec. There are three types of trigger issued by TGC, and they are exclusive. TGC_HALO uses hits from 2 doublet stations. To have acceptance for beam halo which runs in parallel to beam line, two layers on pivot planes in eta direction is used, on the other hand , coincidence of 3 out of 4 layers is applied in phi direction. TGC_MU0 , in addition to TGC_HALO, required 2 out of 3 coincidence in the 1st triplet station. (within full open road) TGC_MU6 , in addition to MU0, requiring the position of 2/3 coincidence be inside the narrower road There are two sharp peaks in the plot. The single beam is going from C to A-side during this period. The difference of time can be under stood as Time-of-flight. The spread of the timing peak is about 1BC, it means the timing alignment is perfectly done at this level. ( Rem : delay parameters have been set with assuming particles are coming from IP, so the direction for C-side is opposite to this assumption. It looks this is the reason why the red peak is spread into 2 bins.) After looking this plot, we shifted global timing by -5BC, it means TGC is set as ready for collision Contact: Masaya Ishino

### L1 Central Trigger (CTP)

 Timing distribution of Level 1 triggers from September 10, the first day of single-beam data. Events were triggered with the BPTX, providing a stable time reference (at BC 0) with respect to the LHC. One should note both the large overlap between triggers (since the beam quality was poor, we observed a large number of calorimeter and muon triggers) and the broad timing distribution of the different trigger sources. Additionally, one can see the 'two-peak' structure in the TGC from the two endcaps, explained in detail in another plot above. Contact: Daniel Sherman Timing distribution of Level 1 triggers from September 12, the third day of single-beam data. Events were triggered here with the MBTS at BC 0. Of note in this plot is the excellent timing of the BPTX and MBTS, and also the relatively small coincidence of the minimum bias trigger with calorimeter and muon triggers. The latter point implies that the beam quality had improved significantly in the first 48 hours of beam time. The timing of the RPC had not been tuned at all prior to this run. Contact: Daniel Sherman Level-1 trigger rates. Data were collected during RUN 87863, triggering on BPTX from beam 2. The plot shows the trigger rate for the BPTX, MBTS single counter, LCID. The rate is averaged over 10 seconds, and it peaks every 40 seconds, the beam injection interval at that time. Contact: Andrea Messina CTP Bunch-Crossing (BC) distribution of the RPC low-pt trigger, from any trigger sector, with respect to the TRT trigger before (run 125636) and after (run 137651) a single time alignment calibration iteration. The residual spread is mainly due to the fact that a coarse (minimum 1 BC level) correction was applied when putting the RPC in time witj the TRT (actually: delay set to +1 BC on purpose) Contact: Michela Biglietti, Giuseppe Salamanna CTP Bunch-Crossing (BC) distribution of the RPC low-pt trigger, with respect to the TRT trigger after (run 137651) a single time alignment calibration iteration, in units of BC, in an RPC Sector vs Tower map. This is equivalent to the previous plot, but is obtained on a subsample of events where only 1 CTP RPC entry and 1 RPC trigger sector+tower were recorded, in order to be able to associate CTP and space information. Contact: Michela Biglietti, Giuseppe Salamanna CTP Bunch-Crossing (BC) distribution of the RPC low-pt trigger, with respect to the RPC trigger sector 39 taken as reference, after (run 131537) a single time alignment calibration iteration, in units of BC, in an RPC Sector vs Tower map. This is equivalent to the previous plot, but is obtained using only RPC information on a run where RPC gave L1 Accept. Contact: Michela Biglietti, Giuseppe Salamanna Eta of the position of the Trigger CM hit (x-axis) vs the Eta of the position of the closest MuCTPi ROI recorded. The closest MuCTPi ROI is the ROI closest in Eta and Phi to the CM hit considered. Both CM-eta and CM-phi are plotted here. When the hit is not matched with a track, a few CM hits display in the plot that are uncorrelated with an actual ROI in that event, being therefore not real triggers (no coincidence satisfied). These disappear when asking for a track match. Contact: Giuseppe Salamanna

### L1 Minimum Bias (MBTS)

 Timing distribution for 6 of the 32 MBTS panels. Data were collected in run 87863, triggering on BPTX from a single beam. The horizontal axis is the same as the TGC plot above, showing the number of bunch crossings delayed with respect to the trigger. With a small amount of single beam data, the timing distribution for each scintillator panel was adjusted to align the MBTS with the BPTX, thereby setting up proper timing for collision data, Contact: Daniel Sherman Comparison of scope traces of analogue MBTS signals out of the TileCal electronics, for a vertical cosmic muon (top) and the collimator splashes (bottom). A roughly vertical cosmic muon yields a signal of about 700 mV amplitude, whereas the collimator splashes resulted in many many charged particles crossing the scintillators saturating the TileCal readout electronics (at -2 V). Note: MBTS stands for Minimum Bias Trigger Scintillators. They are 2x16 scintillator paddles, installed on both sides of the interaction point. See the ATLAS week talks for more details.

### L1 Beam Pickups (BPTX)

 Oscilloscope traces of discriminated beam pick-up (BPTX) signal (C1, yellow) and minimum bias trigger scintillator (MBTS) analogue signals (C2, C3, C4) during an injection of 1 bunch (beam 2) without RF capture. The bunch manages to circulate a few times. After 7 turns its intensity falls below the threshold of the BPTX discriminator. The first few turns gives only small activity in the MBTS. After 3 or 4 turns all MBTS show saturated signals for 5 to 6 turns. Contact: Thilo Pauly Bunch intensity measured by the beam pick-up monitoring system during a coast of more than 20 minutes of beam 2 on Friday 12 Sep 2008 1:11 am. The relative precision determined from the scatter of data points is 10 percent. The absolute intensity value is not calibrated yet and corresponds roughly to unit of 1e10 protons. Contact: Thilo Pauly Oscilloscope traces with persistency set to infinity of: beam pickup (BPTX) signal (C3 blue) of beam 2, discriminated BPTX signal (C4, green), bunch clock of beam 2 (C1 yellow), reference bunch clock (C2 red). The traces were taken during 20 minutes of beam 2 on Friday 12 Sep 2008 1:11 am. The phase between BPTX signal and bunch clock 2 stayed constant within +/- 100 ps (40 ps RMS). The reference clock, which was used by ATLAS at the time, was not in sync with the beam. Contact: Thilo Pauly

## Egamma Slice

 The figure shows the shower shape R_eta used for electron and photon selections calculated at Level-2 and Event Filter. It is calculated by the ratio of the energy deposit in 3x7 cells (corresponding to 0.075 x 0.175 in Delta eta x Delta phi) over 7 x 7 cells in the second EM sampling. Only clusters are shown if the cluster could be matched to an offline cluster with ET>5 GeV. Note, the value of R_eta can have values above one due to the electronic shaping function used in LAr. They are set-up in such a way that noise contributions will fluctuate around zero instead of producing on offset, thus cell energies can obtain negative values. This might result that the total energy deposit in Delta eta x Delta phi = 3 x 7x cells is bigger than the one in 7 x 7 cells in case of small signals. The plot was done using run 90272. It shows nicely the form of the R_eta variable obtained in cosmic data taking and conveys the message the HLT e/gamma trigger is technically functioning. This figure was produced using the ESDs from reprocessing 602. The trigger content is the one from the actual online running. The same figure in eps format: run90272_rcore1d.eps Contact: Monika Wielers The figure shows the shower shape R_eta used for electron and photon selections calculated at Level-2 and Event Filter in a scatter plot. The colour code give the number of clusters found in each bin. Only clusters are shown if the cluster could be matched to an offline cluster with ET>5 GeV. The same information as in the previous figure is displayed. In a conference the previous figure should be shown in preference to this one, however, this figure may be useful in case of questions but will require careful explanation. This figure was produced using the ESDs from reprocessing 602. The trigger content is the one from the actual online running. The same figure in eps format: run90272_rcoreoefl2.eps Contact: Monika Wielers Another shower shape used for electron/jet separation is the search for substructures within one cluster in the first EM sampling which has a very fine-grained granularity in eta. The shower is studied in a window Delta eta x Delta phi = 0.125 x 0.2 and the first E1(max) and second highest maximum E2(max) are searched for. The figure shows the distribution energy in the strip with maximal energy at Level-2 and Event Filter. The clusters come from run 90272 and only clusters are shown if the cluster could be matched to an offline cluster with ET>5 GeV. This plot conveys the message the HLT e/gamma trigger is technically functioning. This figure was produced using the ESDs from reprocessing 602. The trigger content is the one from the actual online running. The same figure in eps format: run90272_emax1d.eps Contact: Monika Wielers

## HLT Tracking

 The following three figures (starting with this one) show L2 event reconstruction efficiency for 2008 cosmic data, separately for the three Inner Detector tracking algorithms that were running at L2. L2 efficiency is defined with respect to an event with an offline track and was measured for the RPC L1 stream since cosmic algorithms at L2 were only used to trigger events from this stream. The offline track is required to have at least three silicon space points (SP, number of pixel hits plus the number of SCT hits divided by two) in the upper and three in the lower part of the silicon barrel. Either of the two track arms can be independently reconstructed at L2 by silicon algorithms. If there is more than one such track in an event, the track with most pixel hits is used as a reference (most SCT hits if there are no pixel hits). We require |d0| < 200 mm for plots other than d0 dependency. The track is also required to be within Transition Radiation Tracker (TRT) read-out time window. This is required due to large RPC trigger jitter. TRT detector is reading out three bunch crossings (BC). TRT is operating on a principle of a drift chamber, where time of arrival of the signal varies over the range of about 50ns, depending on the track to wire distance within the TRT detector element (straw). Therefore, optimal time window for TRT detector is even considerably smaller than 75ns (three BC). Outside the optimal range, hits have either poor tracking accuracy or are lost completely. This has clear impact on the track reconstruction efficiency as can be seen in the figure. For plots other than this one we therefore require -10ns < TRT EP < 25ns. L2 reconstruction efficiency as a function of TRT EP. Different symbols indicate different L2 algorithms as shown in the legend. TRT L2 efficiency falls off sharply at the edge of TRT read-out time window. Events with invalid EP (mostly events that have no TRT hits on track) are not shown in this plot. With |d0| < 200mm requirement. The same figure in eps format: L2eff.CombinedInDetTracks_CTB.ep.goldenSi_200.eps Contact: Sasa Fratina L2 reconstruction efficiency as a function of track impact parameter d0. Different symbols indicate different L2 algorithms as shown in the legend. With -10ns < TRT EP < 25ns requirement. The same figure in eps format: L2eff.CombinedInDetTracks_CTB.d0.goldenSi_3.eps Contact: Sasa Fratina L2 reconstruction efficiency as a function of track transverse momenta pT. pT for cosmic tracks is defined in the same way as for collisions: pT = | sin(theta) * p |, where theta is the angle between the track trajectory and the beam axis. Different symbols indicate different L2 algorithms as shown in the legend. Track selection -10ns < TRT EP < 25ns and |d0| < 200mm is used. The low efficiency for IDScan at the lowest-PT bins is expected (and intentional): The spacepoint shifter used before the pattern recognition works for more-or-less straight tracks in the inner detector. The same figure in eps format: L2eff.CombinedInDetTracks_CTB.pt.goldenSi_203.eps Contact: Sasa Fratina An example of the Tier-0 Monitoring for IDScan. The histogram is the IDScan phi_0 distribution for tracks from the IDCosmic stream where phi_0 is the track tangent angle at the track perigee, the point of closest approach to the origin. This clearly shows the top-to-bottom nature of the events with the two trigger tracks reconstructed approximately at +pi/2 and -pi/2. Figure as better quality eps file Contact: Mark Sutton The distribution of the IDScan track impact parameter with respect to the beamline position for events from the IDCosmic stream from the Tier-0 monitoring, clearly showing the acceptance of the SCT and Pixel detectors used for the pattern recognition. Figure as better quality eps file Contact: Mark Sutton The distribution of IDScan track z0 for events from the IDCosmic stream from the Tier-0 monitoring, clearly showing the acceptance of the SCT and Pixel detectors used for the pattern recognition. Figure as better quality eps file Contact: Mark Sutton The distribution of SiTrack track z0 for events from the IDCosmic stream from the Tier-0 monitoring, clearly showing the acceptance of the SCT and Pixel detectors used for the pattern recognition, and a large spike due to the presence of fake tracks due to a noisy module which illustrates the role of the monitoring in correcting routine problems of this nature which might otherwise affect data quality. Figure as better quality eps file Contact: Mark Sutton a cosmic event showing the two L2 tracks which can be seen clearly from the close up of the pixel detector in the top right. This event was taken from run 901272. Figure as better quality pdf file Contact: Mark Sutton The following three plots show the per track efficiency to reconstruct Event Filter tracks with respect to offline tracks for run 91862 (solenoid on). Loose, medium and tight cuts are applied to the offline tracks. Loose: >=8 barrel silicon hits OR >=30 barrel TRT hits, pT > 1 GeV, d0 < 500 mm, -10ns < TRT Event Phase < 40ns. Medium: >=10 barrel silicon hits, >=20 barrel TRT hits, pT > 1 GeV, d0 < 250mm, -5ns < TRT Event Phase < 30ns. Tight: >=4 barrel pixel hits, >=12 barrel SCT hits, >=50 barrel TRT hits, pT > 1 GeV, d0 < 40mm, -5ns < TRT Event Phase < 30ns. Silicon hits is defined as 2*NPixelHits + NSCTHits. Events are from the IDCosmic stream, which is triggered by the muon chamber at L1, and found to have an inner detector track at L2. The dashed line shows the overall efficiency. This is 83.0% for loose tracks, based on around 18k tracks. Figure as better quality eps file Contact: Jenna Lane For medium tracks, the overall efficiency is 99.7% based on around 6k tracks. Figure as better quality eps file Contact: Jenna Lane For tight tracks, the overall efficiency is 100% based on around 450 tracks. Figure as better quality eps file Contact: Jenna Lane The following four plots show the per track efficiency to reconstruct Event Filter tracks with respect to offline tracks for run 92048 (solenoid off). Loose, medium and tight cuts are applied to the offline tracks. Loose: >=8 barrel silicon hits OR >=30 barrel TRT hits, pT > 1 GeV, d0 < 500 mm, -10ns < TRT Event Phase < 40ns. Medium: >=10 barrel silicon hits, >=20 barrel TRT hits, pT > 1 GeV, d0 < 250mm, -5ns < TRT Event Phase < 30ns. Tight: >=4 barrel pixel hits, >=12 barrel SCT hits, >=50 barrel TRT hits, pT > 1 GeV, d0 < 40mm, -5ns < TRT Event Phase < 30ns. Silicon hits is defined as 2*NPixelHits + NSCTHits. Events are from the IDCosmic stream, which is triggered by the muon chamber at L1, and found to have an inner detector track at L2. The dashed line shows the overall efficiency. This is 81.6% for loose tracks, based on around 18k tracks. Figure as better quality eps file Contact: Jenna Lane For medium tracks, the overall efficiency is 99.8% based on around 6k tracks.

Figure as better quality eps file Contact: Jenna Lane The loose offline track requirement allows TRT only tracks. At the time of the data reprocessing, the Event Filter was not running any TRT-only tracking. Here, the hit requirement on the offline tracks is modified to be >=8 Si hits to remove the TRT only tracks. For loose Si tracks, the overall efficiency is 98.0% based on around 10k tracks. Figure as better quality eps file Contact: Jenna Lane The following four plots show the track parameters of Event Filter cosmic tracks from 100k events of run 121419 (2009 data taking). The tracks shown are only from the inside-out tracking, selected by requiring >= 1 silicon hit on the EF track. TRT-only tracks are not included. Sharp peaks due to noisy modules are seen, in particular in the d0 and z0 distributions. The small number of events with positive phi arise when the EF fits a cosmic as two separate tracks.

Shown are the pixel (turquoise), SCT (blue) and TRT (purple) detectors. The SCT hits are shown as short bars, in orange if they are associated with the track, yellow otherwise. The TRT hits are shown as small dots - orange if associated with the track, white otherwise. The circular surface is to display the TRT barrel hits, since the TRT barrel doesn't measure the z co-ordinate. The TRT endcap hits are displayed on the cylindrical surface, since the TRT endcap doesn't measure the radius from the beampipe. Here, the track pT is measured by the EF as 7.4 GeV.

Only tracks from the inside-out tracking were included. (InDet Tracks) These were preselected by requiring EF and offline tracks to have >= 1 silicon hit Loose, medium and tight cuts were then applied to the offline tracks.

Data preparation (bytestream decoding and clustering) were fully-ported to the GPU and all steps of SiTrack (except for track duplicate merging/removal) were ported to the GPU. Primary vertex reconstruction in SiTrack was not performed. The first plot shows the performance comparison for data preparation (bytestream decoding and clustering). The test was run on high-luminosity ttbar MC. Contact: Jacob Howard The second plot shows the performance comparison for tracking (SiTrack). The test was run on high-luminosity ttbar MC. Contact: Jacob Howard The third plot shows the throughput of the full chain of data preparation and tracking in the tau slice on high-luminosity ttbar MC as a function of the number of Athena trigger processes.

## Tau Slice

 ATLAS event display for run 90272, event 2895570, triggered by tauNoCut trigger signature, in L1Calo stream. RoIs triggered under such signature have at least 5 GeV energy deposition at L1. The RoI triggered in this event has also a track reconstructed at HLT step, pointing close to nominal interaction region. The HLT calorimeter deposit as well as the track reconstructed are both shown in the event display. Run 90272 is from September 2008, and the event display software used is VP1, using ESD from HLT reprocessing of BS data at Tier0. Contact: Olya Igonkina ATLAS event display for run 90272, event 4524774, triggered by tauNoCut trigger signature, in L1Calo stream. RoIs triggered under such signature have at least 5 GeV energy deposition at L1. The RoI triggered in this event has also a track reconstructed at HLT step, pointing close to nominal interaction region. The HLT calorimeter deposit as well as the track reconstructed are both shown in the event display. Run 90272 is from September 2008, and the event display software used is VP1, using ESD from HLT reprocessing of BS data at Tier0. Contact: Olya Igonkina ATLAS DQ monitoring for the tau slice for run 92226, taken in October 2008. The reference plots shown in blue are taken for a good run (92054), while the red/green plots show data with unusual/usual distribution. The shifter tracks unusual transverse hadronic energy distribution at L2 for tau candidates. This was identified as a problem in configuration of calibration trigger items (trk9i_calib) which did not ignored laser pulses for calibration of hadronic calorimeter. This was identified on-lined and fixed within short period of time. Contact: Olya Igonkina The tau trigger performance is checked with respect to the offline reconstruction. The plots show the pT difference as a function of EF tau (top) and the energy correlation between trigger and offline reconstructions (bottom). No eta dependence was found. The difference is within the expected difference between trigger and offline reconstruction at the cell level comparison. The EF show a reasonable performance with respect to the offline reconstruction. Contact: Soshi Tsuno The tau trigger performance is checked with respect to the offline reconstruction. The plots show the pT difference as a function of EF tau (top) and the energy correlation between trigger and offline reconstructions (bottom). The difference is within the expected difference between trigger and offline reconstruction at the cell level comparison. The EF show a reasonable performance with respect to the offline reconstruction. Contact: Soshi Tsuno The tau trigger reconstruction consists of the clusters in the EM and hadronic calorimeters, and the tracks associated in the tau object. This gives us an unique oppotunity to get handle the MIP cluster in the tau. By asking the extrapolated track on the surface of the calorimeter to be matched with the cluster with 20cmx20cm rectangular region, the MIP cluster is identified. Figure presents the energy distributions of the MIP cluster in the EF tau. There are three peaks at 1, 3 and 10GeV in the MIP cluster energy distribution. The 10GeV peak is that the MIP cluster itself ﬁres the trigger with threshold above 5GeV. The rest of them are less energetic cluster but the large cluster exists in neighbor of the MIP cluster, then sum of cluster energy in the tau object exceeds the trigger threshold. Note that the number of clusters associated in the tau object in ∆R≤0.4 is not always one. Contact: Soshi Tsuno
