Introduction

The MS commissioning and performance plots below are approved to be shown by ATLAS speakers at conferences and similar events.

Please do not add figures on your own. Contact the MS project leader in case of questions and/or suggestions.

Figures

Figures 1 to 6 are coloured versions of Figures 10.32, 10.33, 10.35, 10.36, 10.37, 10.38 published in the ATLAS detector paper
published in JINST 3:S08003,2008.

Nomenclature used in Figures 1 to 6:
  • stand-alone = muon reconstructed with the muon spectrometer stand-alone; the muon momentum is corrected for the energy loss in the calorimeters by the expected energy loss;
  • combined = muon reconstructed with the muon spectrometer and the inner detector;
  • all = stand-alone + combined muons + inner detector tracks tagged by track segments in the muon spectrometer.

Fig. 1: For muons with pT = 100 GeV, expected fractional momentum resolution as a function of the pseudrapidity for stand-alone and combined reconstruction. The degradation in the region with 1.1 < |n| < 1.7 is due to the absence of the middle muon stations in the barrel/end-cap transition region for the initial data-taking, to the low bending power of the magnetic field in the transition region between the barrel and end-cap toroids and to the material of the coils of the end-cap toroids.

Fig. 2: For muons with pT = 100 GeV, expected fractional momentum resolution as a function of the azimuth for stand-alone and combined reconstruction. The resolution is degraded at 240° and 300° , due to the additional material introduced by the feet which support the barrel part of the detector.

Fig. 7: The plot shows the measured sagitta, in the precision plane, for cosmics taken without magnetic field in the middle barrel chamber BML2C03 of muon spectrometer. For a properly aligned tower the mean value of the sagitta is expected to be inside required 30 microns level. The three plots show the sagitta distribution for three different geometries : the red distribution is obtained using nominal geometry, the blue one using the optical alignment system based geometry and the green one is obtained after alignment with straight tracks ( for further details please contact potrap@mppmuNOSPAMPLEASE.mpg.de).

Fig. 8: The plot shows "track" sagittas calculated from segments in the stations EI-EM-EO before and after applying alignment corrections determined by the optical alignment system of the endcaps. We do not actually use any of the tracking algorithms, instead we define as a "track" a triplet of segments that have passed our selection cuts. The sagitta is then calculated in the usual way as the distance in the precision coordinate of the EM segment from the line joining the EI-EO segments.

The "nominal chamber positions" histogram reflects the positioning accuracy that we have reached in the endcaps - typically 5mm rms in all coordinates for the chambers within a wheel, but up to 25mm displacements of entire wheels along ATLAS-Z. The EM station is displaced significantly along ATLAS-Z on the A-side, but not on the C-side, which is the main contribution to the difference between sides A and C.

The "after alignment corrections" histogram should, for the optical alignment to be ok, be centered at zero and have a width that can be explained by effects other than random chamber misalignment. We observe a mean value of -48 +/- 54mu, thus compatible with zero, and a width of 1.5mm, compatible with the expected multiple-scattering width (as a benchmark, for 40GeV muons at theta=30 degrees the expected width from a single-muon simulation is 1.4mm).

We conclude that, with the statistics available at this moment, we see no indication of the optical alignment being not ok within the claimed accuracy of 45-50mu.

Fig. 9: The plot shows the difference in angle (in the precision coordinate) of the three segments of a "track" from the line joining the EI and EO segments. Each "track" = segment triplet contributes three entries to the histogram. We cut at +/-10mrad in this plot in order to remove background from wrong segment combinations (this also discards very-low momentum muons).

Segment positions (being some sort of average over all the hits in a chamber) are much less affected by calibration (t0 and r(t) function) than segment angles (being some sort of difference between hits), and thus the width of this distribution, even after alignment corrections, is significantly larger than expected from simulation (for 40GeV muons at theta=30 degrees the expected width is around 0.5mrad).

Fig. 11: The plot shows the global occupancy of MDT multilayers over the full detector divided in INNER, MIDDLE, and OUTER layer of chambers

Fig. 12: The plot shows the Residuals for MDT chambers after applying T0 refit on cosmic muons, the residuals have been fitted with a double gaussian and the narrower one is 105 micron wide.

Fig. 13: The plot shows the hit profile and the efficiency for an MDT barrel sector, both from the hit profile and the efficiency plot the presence of a dead wire is visible.

Fig. 14: Segment efficiency per MDT chamber for cosmics.

Efficiency is determined using Muon Spectrometer tracks with segments in two or more station layers (Inner/Middle/Outer). By selecting one layer, for example the Inner layer, and requiring a track with segments in the Middle and Outer layers that crosses the Inner layer, the number of missed segments in the Inner layer and the corresponding efficiency is determined. Note that the segment (here in the Inner Layer) is not required to lie on the track. For the extrapolation an ideal cilinder without chamber cut outs is used. This means that in the feet region and the RIBs small inefficiencies are expected due to the limited chamber coverage.

Results are for Mdt chambers after acceptance and minimum number of events cuts BI BO station |eta| = 2-4 and EI |eta| = 1-2, EO EM and BM no cuts, one chamber was removed. Results after these cuts for 322 Barrel and 339 Endcap chambers.

Average segment efficiency Barrel Inner 98.7 % Barrel Middle 99.2 % Barrel Outer 99.6 % Endcap Inner 99.2 % Endcap Middle 99.8 % Endcap Outer 99.9 % Total average segment efficiency 99.5 ± 0.5 %



Fig. 15: Plot shows segment efficiency for station eta vs phi, for the Barrel Middle MDT chambers (BM). The method is described in caption of Fig 14. The RIB structure can be observed.

Fig. 17: Status of the coverage for the Low Pt trigger in the Barrel for a cosmic run taken in September 2009.

Fig. 18: Cosmics muon map reconstructed by off-line RPC standalone muon monitoring projected on surface (y=81m).The tracking is based on RPC space points, which are defined by orthogonal RPC cluster hits. The pattern recognition is seeded by a straight line defined by two space points belonging to the two Middle planes. Space points not part of any previous track and inside a predefined distance from the straight line are associated to the pattern. Patterns with points in at least 3 out of 4 layers in Middle planes are retained and a linear interpolation is performed in the two orthogonal views.

Fig. 19: Spatial correlation between MDT tubes and RPC eta hits with cosmic data.The picture shows the scatter plot between MDT tubes z coordinate and RPC eta hits z coordinate of the same chamber along sector 7 for the Middle chamber. There is no clean-up cuts but an ADC cut > 50 on MDT Front-end response to reject MDT random hits. The blue squares are due to uncorrelated hits and show the station geometrical boundary along the z-axis.

Fig. 20: Time alignment inside Low Pt trigger towers in phi view with cosmic data.The plot shows the distribution of the relative time between RPC layers of Low Pt non-bending view coincidence matrix delivering one and only one hardware trigger in the event. The time is relative to the layer nearest to the IP.

Fig. 21: RPC distribution of single channel noise counting rate per unit area measured with random triggers. The noise is referred to the front-end channel and is calculated by the total number of hits divided by the total number of random triggers and the readout window (200 ns) normalized by the equivalent strip surface. The definition of the equivalent strip surface takes into account the wire-or and the logical-or in phi view.

Fig. 22: Distribution of RPC hits per event with RPC cosmic trigger (not filled area) and with random trigger (black filled area). The distributions correspond to the RPC detector occupancy due to cosmics and uncorrelated noise.

Fig. 23: RPC spatial correlation between trigger strip number and confirm strip number in phi view for a programmed trigger road in cosmics data. The trigger strip corresponds to the Pivot plane strip which caused the trigger to fire for the given threshold. The confirm strip corresponds to the Low Pt plane of the triggered chamber. It is possible to see the trigger road projective pattern by the deviation of the data points from the dashed line. Strip number 0 corresponds to the center of the geometrical sector.

Fig. 24: TGC hits distribution in x-y plane for A side on run 91060. Hit positions are calculated from coincidence of wire eta hits and strip phi hits. Only bottom sectors (sector 8~12) are used for triggerring (eps file also found with the same name)

Fig. 25: TGC hits distribution in x-y plane for C side on run 91060(upper) and 91803(lower). Hit positions are calculated from coincidence of wire eta hits and strip phi hits. Only bottom sectors (sector 8~12) are used for triggerring (eps file also found with the same name)



Fig. 26: TGC trigger readout distribution (or latency) for TGC triggered events on run 91060. Three bunch crossing (BC) data, previous, current and next BC, are read out. More than 99% of events are in current BC. This means that we are reading the data in pipeline with correct latency. (This does not mean that trigger timing btw TGC and other subtrigger is aligned. ) Rest of less than 1% events are, we guess, due to cosmic showers. (eps file also found with the same name)

Fig. 27: Number of TGC hits per event for TGC stream (which contains RPC triggerred events. About 20% of events are RPC triggerred since RPC sector logic got crazy and sent the events to TGC stream...) on run 91060.. Both wire and strip hits in current BC are counted. Mean value of 53 hits is much smaller than number of channels 300 thousand events. This proves cleaness of TGC chambers. (eps file also found with the same name)

Fig. 30: Correlation btw MDT tube hits in middle station and TGC track interpolated to MDT middle station for A side on run 91060. TGC tracks are reconstructed with wire hits and required at least 3 station hits. Clear correlation is seen. Vertical lines are due to noisy MDT tube while horizontal lines are due to noisy TGC wires. (eps file also found with the same name)

Fig. 31: Correlation btw MDT tube hits in middle station and TGC track interpolated to MDT middle station for C side on run 91060.

Fig. 32: The plot shows TGC layer efficiency as a function of applied High-Voltage. The event sample (= denominator of eff.) is selected based on the MDT track-segment and corresponding 3-wire hit channels for the case of TGC2 / TGC3 (2-wire hit channels for the case of TGC1) , and the efficiency of the last 4th (3rd) layer is evaluated.

Fig. 33: TGC Frontend readout timing (or latency) for TGC triggered events on run 91060. Three bunch crossing (BC) data, previous, current and next BC, are read out. More than 98% of events are in current BC. This means that we are reading the data in pipeline with correct latency. (This does not mean that readout timing btw TGC and other subtrigger is aligned. ) Rest of less than 1% events are, we guess, due to cosmic showers. (eps file also found with the same name)

Fig. 34: (a) TGC efficiency map for layer 5, T7 chamber. The horizontal axis is the strip channel and the vertical axis is the wire channel. (b) Efficiency projection to the strip channels. The blue bands show the strip channels which contains the wire support structure in its channel (dead region). Observed efficiency drops are consistent with the location of wire support location.

Fig. 35: TGC wire efficiency vs high voltage (for active region). Circle mark shows the combined run result in 2008, while square mark shows the beam test results in 2003. The difference of altitude (80m) is taken into account. Both results are consistent within 1%.

Fig. 61: RPC cluster size for the horizontal sectors of the barrel muon spectrometer. A dependency on sector angular position with respect to the vertical cosmics is visible by comparison with the distribution in vertical sectors (see fig. 62). No runs with uniform HV at the nominal voltage of 9600 Volts was available, therefore a run taken at 9400 V was chosen.

For muons coming from the interaction point a flat behaviour is expected with a mean value close to the minimum of the present plot. Eta (Blue) and Phi (Red) panels are shown separately. Phi panels show a slightly higher cluster size than eta panels as expected from detector construction; an additional PET sheet is inserted in between the gas volume and the eta readout panel.

Fig. 67: RPC pivot plane response for a splash event coming from ATLAS side A (right side of the plot).The black areas are due to the toroid legs in sector 12 and 14, to the toroid ribs along the even sectors and to the crack for the services at eta=0. The few white holes are due to detector regions not operated during the splash.

Eta and Phi coordinates are given in terms of Muon Station sector and position in eta. The fractional values are given by the gap position within the station. The three layers of chambers (Low_Pt, Pivot and High_Pt) at increasing distance from the beam axis are shown separately.

The black curve is a fit of a double-Gaussian distributions with four parameters; the mean values of the two single Gaussians are set to the same value, and they are normalized to the same area. The mean values are -15 +/- 19 mu for the sum of both endcaps (as shown on the plot), -28 +/- 22 mu for side A, and -11 +/- 38 mu for side C (both not shown here). The width of the distribution is dominated by multiple scattering, and indicates that the typical momentum of the cosmic muons in this plot is around 100 GeV.

Fig. 92: Mean values of sagitta distributions for individual sectors, plotted versus the sector number. To produce this plot, histograms like the one in Fig. 91 were created for each sector and fitted with a double-Gaussian function. The red-hashed sectors 16/01/02 and 08/09/10 are so poorly illuminated by cosmics that no meaningful results can be obtained. The straight black line is the "fit" of a 0-th order polynomial with its only free parameter fixed at zero; the chi2/ndf of the fit is thus a measure of how well the individual sector mean values are compatible with a common mean at zero. The errors of the mean values are statistical only, and they are significantly larger than the intrinsic accuracy of the optical alignment, in other words: this analysis is currently statistics-limited.
