| In the following, performance studies of Micromegas detectors performed with test-beams on several small (10x10 cm2) / medium(1x0.5 m2) size resistive chambers will be reported. In particular the chambers that will be referred to are:
|  |
| Fig. 1: Integrated charge for one APV channel for a single event Typical integrated charge from one MicroMegas strip readout with the APV25 hybrid cards (through the Scalable Readout System) operated at 40 MHz with 27 samples. A fit with a Fermi-Dirac function with an additional baseline is performed to determine the strip-hit time, which is defined as the inflection point of the fitted function. Strip-hit charge is measured in the anlayses from the maximum of this distribution or from the plateau of the FD function, in both cases subtracting the fitted baseline. pdf1 pdf2 |  |  |
| Fig. 2: Event display (μTPC and Centroid) Display of an event acquired with chamber T4 on particles with a 30 degrees inclination during a test beam at H4. (Bottom) charge read by each of the strips. (Top) reconstructed centroid and μTPC track. |  |
| Fig. 3: Efficiency map 2D hit reconstruction in a Tmm chamber during a high statistics run. For this study the chamber was kept perpendicular to the beam axis. The hit position in both X and Y readouts is calculated using the centroid method and only events with a single cluster per readout (perpendicular tracks) are used. The inefficient spots appearing every 2.5 mm, corresponding to the pillar structure supporting the mesh of the chamber, are visible. Four different representations of the same plot are shown. The measurements were performed with a Tmm type MM bulk resistive chamber operated with an amplification voltage of HVamp = 540 V. The data were acquired during PS/T9 with a 10 GeV/c π+/p beam. pdf1 pdf2 |  |  |
| Fig. 4: Efficiency map Hit reconstruction efficiency as a function of the extrapolated reference track hit position for a 2D readout chamber of Tmm type. The reference track is reconstructed from 3 Tmm chambers and is then extrapolated to the fourth Tmm under study. Left column corresponds to X and right column corresponds to Y. The first row shows the efficiency for an irradiated area 20 mm wide. The efficiency dips 15% appearing every 2.5 mm correspond to the pillar structure supporting the mesh. The second row focuses only on selected areas on the Y readout of the chamber which are around the pillar region (bands 500μm). The effect of the pillars is more severe in these regions reaching local efficiency dips of the order of 40%. By scanning only the region in between the pillars the efficiency is uniform along the readout channels and a high efficiency is measured for both layers (above 98%). The Y readout shows higher efficiency owing to the fact that it is right below the resistive strips and thus it accumulates more charge than the X layer. The measurements were performed with a Tmm type MM bulk resistive chamber operated with an amplification voltage of HVamp = 540 V. The data were acquired during PS/T9 with a 10 GeV/c π+/p beam. |  |
| Fig. 5: Efficiency map Hit reconstruction efficiency as a function of the extrapolated reference track hit for 2 small T type bulk resistive MM chambers namely TQF, T2. The reference track is reconstructed from 4 Tmm chambers and is then extrapolated to the chamber under study. The two plots on the left correspond to data acquried with the chambers perpendicular to the beam axis while for the two right plots the chambers were inclined by 30 degrees. In both cases the centroid method is used for the reconstruction of the hits. The efficiency dips (5%) appearing every 5 and 2.5 mm respectively correspond to the pillar structure supporting the mesh. The pitch between the pillars and their size are different for the two chambers under study as it is evident from the plots. The TQF chamber has 500 μm wide pillars with a pitch of 5 mm while the T2 pillars are $300μm wide with a pitch of 2.5 mm. In the case of the inclined chambers the particles traverse the chambers under an angle inducing signal in larger number of strips compared to the 0 degrees case. In this case the efficiency is expected to be unaffected by the pillars as it is shown on the two plots corresponding to the 30 degrees case (above 99%). The measurements were performed with T type MM bulk resistive chambers operated with an amplification voltage HVamp = 540 V. The data were acquired during PS/T10 with a 6 GeV/c π+/p$ beam. pdf1 pdf2 |   |
| Fig. 6: Effect of the pillars on the hit reconstruction Apart from the efficiency the pillar structure affects also the hit reconstruction intriducing a bias in the hits reconstructed in their region. This effect (bias) is studied using a set of three Tmm chambers to reconstruct a reference track which is then extrapolated to a fourth Tmm chamber. Chambers are kept perpendicular to the beam and the hit in each chamber is reconstructed using the centroid method. In the top plot, the residuals between the hit reconstructed in the chamber under study and the reference tracks are plotted versus the reconstructed hit position. In the bottom plot the reconstructed 2-D hit position in the same chamber is plotted. The position of the pillars is clearly visible in the bottom plot and the observed bias in the reconstructed hit position can be associasated with the position of the pillars comapring the two plots. The bias is evident in each pillar region with a maximum value 150μm. The measurements were performed with Tmm type MM bulk resistive chambers operated with an amplification voltage HVamp = 540 V. The data were acquired during PS/T9 with a 6 GeV/c π+/p$ beam. |  |
| Fig. 7: Spatial resolution of precision coordinate of Tmm/Tmb chambers Residual distributions from the hit position difference between a Tmm and a Tmb chamber, divided by √2 (assuming similar resolution for both chambers sice the effect of the different pillar pattern is negligible), featuring a 2D readout. The left plot corresponds to the residuals of the X readouts while the right one shows the Y hit residuals. For this measurement the chambers were kept perpendicular to the beam and the hit reconstruction was done using the centroid method selecting single cluster events in both chambers. A similar performance, in terms of spatial resolution, for X and Y readouts is observed. σcore corresponds to the width of the core gaussian while σweight is the weighted average of the two gaussians σweight2=fcoreσcore2+ftailsσtails2, fcore,tails=pcore,tailsσcore,tails/(pcoreσcore+ptailsσtails) The measurements were performed with Tmm and Tmb type MM bulk resistive chambers operated with an amplification voltage HVamp = 540 V. The data were acquired during SPS/H4 testbeam with a 150 GeV/c μ/π+ beam. pdf1 pdf2 |  |  |
| Fig. 8: Spatial resolution of the T chambers Residual distributions from the hit position difference between two T type MM chambers (T2,T4) , divided by √2. For this measurement the chambers were kept perpendicular to the beam and the hit reconstruction was done using the centroid method selecting single cluster events in both chambers. σcore corresponds to the width of the core gaussian while σweight is the weighted average of the two gaussians σweight2=fcoreσcore2+ftailsσtails2, fcore,tails=pcore,tailsσcore,tails/(pcoreσcore+ptailsσtails) The measurements were performed with T type MM bulk resistive chambers operated with an amplification voltage HVamp = 550 V.The data were acquired during SPS/H4 testbeam with a 150 GeV/c μ/π+ beam. |  |
| Fig. 9: Spatial resolution of precision coordinate of the MMSW The MMSW is the Micromegas Quadruplet Prototype. Residuals between the first and the second layer of the MMSW, both with strips measuring the precision coordinate, divided by √2 (assuming similar resolution for both layers). σcore corresponds to the width of the core gaussian while σweight is the weighted average of the two gaussians σweight2=fcoreσcore2+ftailsσtails2, fcore,tails=pcore,tailsσcore,tails/(pcoreσcore+ptailsσtails) The measurements were performed with the MMSW quadruplet operated with an amplification voltage $HVamp = 580 V. The data were acquired during PS/T9 with a 6 GeV/c π+/p$ beam. |
 |
| Fig. 10: Spatial resolution of precision coordinate of the MMSW Left: Residuals between the second and the combination of the two stereo readout layers. Right: Residuals between the first and the combination of the two stereo readout layers. The residuals are divided by √1.5 (assuming similar resolution for all 3 layers) because the second hit is reconstructed by combining the two stereo layers (T.Alexopoulos et al., ATL-MUON-INT-2014-005}).\The observed degradation of the measured spatial resolution is mainly owing to the multiple scattering in the material between the layers under study and thus is proportional to the distance separating them (L1,2<L2,34<L1,34). The worse resolution measured compared to the Tmm case is mainly attributed to the different strip pitch. σcore corresponds to the width of the core gaussian while σweight is the weighted average of the two gaussians σweight2=fcoreσcore2+ftailsσtails2, fcore,tails=pcore,tailsσcore,tails/(pcoreσcore+ptailsσtails) The measurements were performed with the MMSW quadruplet operated with an amplification voltage $HVamp = 580 V. The data were acquired during PS/T9 with a 6 GeV/c π+/p$ beam. pdf1 pdf2 |  |  |
| Fig. 11: Spatial resolution of second coordinate of the MMSW Left : Residual distributions from the hit position difference between the 2nd coordinate hit, reconstructed using the stereo readout 3 and 4 layers of MMSW, with a 2nd coordinate hit reconstructed in one reference chamber at a distance 20 cm from the first plane of the MMSW. Both chambers wee perpendicular to the beam axis and the hit per layer is reconstructed using the centroid method. Right : MC simulation of the ratio between the resolution of the 2nd hit reconstructed combining two stereo layers with the precision coordinate resolution of each stereo layer as a function of the stereo angle value (T.Alexopoulos et al., ATL-MUON-INT-2014-005 ). For a stereo angle of 1.5 degrees, as in the MMSW case, we expect this ratio to be 27 which is in good agreement with our measurement.σcore corresponds to the width of the core gaussian while σweight is the weighted average of the two gaussians σweight2=fcoreσcore2+ftailsσtails2, fcore,tails=pcore,tailsσcore,tails/(pcoreσcore+ptailsσtails) The measurements were performed with the MMSW quadruplet operated with an amplification voltage $HVamp = 580 V.

| Fig. 12: μTPC refinement - Angular Dsitributions Angular distributions reconstructed with a T type MM chamber with the μTPC method for four different chamber inclination angles with respect to the beam axis (10, 20, 30, 40 degrees). The long tails correspond to badly reconstructed tracks because of wrong timing determination or owing to clusters with small number of strips. The mean reconstructed angle is estimated by fitting a gaussian on the peak of the distribution. The angular resolution (width of the gaussian) improves with increasing the incidence angle of the track owing to the fact that there is a larger number of points (strips) to be used for the reconstruction of the track. The measurements were performed with T type MM bulk resistive chambers operated with an amplification voltage HVamp = 510 V.The data were acquired during SPS/H4 testbeam with a 150 GeV/c μ/π+ beam. pdf1 pdf2 pdf3 pdf4 |

| Fig. 13: μTPC refinement - Angle Reconstruction and Spatial Resolution Left: Comparison of the mean reconstructed angle for different chamber inclination angles with respect to the beam axis before (blue markers) and after (red markers) the refinement of the μTPC method. When the μTPC method is corrected for the effect of the capacitive coupling between neighboring strips and the charge position assignment in the edges of the cluster a significant reduction in the observed mean reconstructed angle bias is observed. The remaining bias is attributed to the remaining effect of the capacitive coupling between the middle strips of the cluster. Right: Comparison of the spatial resolution measured for different chamber inclination angles with respect to the beam axis (blue markers) and after (red markers) the refinement of the μTPC method. The refinement of the μTPC method results in a siginficant improvement in the measured spatial resolution (especially for the 10, 20 degrees case). The residual distributions that are used for the extraction of the resolution are fitted with a double gaussian to take into account also the tails. For the resolution plot shown here the resolution is defined as the σ of the core gaussian. The measurements were performed with T type MM bulk resistive chambers operated with an amplification voltage HVamp = 510 V.The data were acquired during SPS/H4 testbeam with a 150 GeV/c μ/π+ beam. pdf1 pdf2 |

Charge clusters are defined as a collection of contiguous strip hits read out within a time window of 3 BCID (75 ns). The charge clusters selected for analysis must be made up of neighbour-triggered hits from the outer strips and above-threshold hits from the inner strips which implies a minimum strip multiplicity of 3. Charge clusters with strip-multiplicities below or equal to 5 are used for the analysis of X-ray data. |

The raw centroid positions, denoted ycl, are shown in (a-d) and the centroid positions corrected for differential non-linearity (DNL), denoted y'cl, shown in (e-h). The DNL bias is corrected using the formula y'rel = yrel + ΣNi=1 ci / (2πi) sin( 2πiyrel) where y'rel and yrel are the cluster centroid positions relative to the nominal strip edges. An independent correction with N=3 is applied for each strip multiplicity. The coefficients ci used for the correction are obtained based on the distributions of yrel of the run. Only clusters from the strips located in the plateau of the X-ray irradiation profile are shown and used for the calculation of the coefficients ci. The pink dashed lines highlight the nominal edges of the strips. During the run, the module is flushed with pure CO2 and operates at 2.925 kV.

The raw centroid positions, denoted ycl, are shown in (a-d) and the centroid positions corrected for differential non-linearity (DNL), denoted y'cl, shown in (e-h). The DNL bias is corrected using the formula y'rel = yrel + ΣNi=1 ci/(2πi) sin(2πiyrel) where y'rel and yrel are the cluster centroid positions relative to the nominal strip edges. An independent correction with N=3 is applied for each strip multiplicity. The coefficients ci used for the correction are obtained based on the yrel distributions of runs without collimator. The pink dashed lines highlight the nominal edges of the strips. The distribution of Fig. (h) is fitted to a Gaussian function. The mean parameter μfit of the fitted function is used as the centroid position of the X-ray profile. During the run, the module is flushed with pure CO2 and operates at 2.925 kV.

The X-ray gun is inserted in the holder piece. A square edge is glued to the surface of the wedge to guide the movement of the holder. The charge clusters making up the irradiation profile are corrected for differential non-linearity using correction coefficients obtained with an X-ray run without the collimator. The measurements are fitted to a first-order polynomial with the slope fixed to unity. The fit residuals, shown in the bottom panel, are consistent with a spatial resolution better than 40 microns.

| Fig. 1: Performance of sTGC serializer: "Eye" diagram The sTGC trigger data serializer (TDS) ASIC chip is responsible for the preparation of trigger data for both pads and strips with additional task of serializing data for transmission to the circuits on the rim of the NSW detector. The serializer is realized in IBM 130 nm CMOS technology. It is adapted from the CERN GBT serializer, with changed architecture from loading 120 bits at 40 MHz to loading 30 bits in parallel at 160 MHz. The serial output is at 4.8 Gbps. The eye diagram is evaluated in a 12.5 GHz bandwidth, 50 GS/s oscilloscope with a PRBS-31 pattern. The height of the eye is measured to be about 540 mV, and the width is about 180.3 ps. Jitter analysis shows that the total jitter at a bit-error-ratio (BER) of 1E-12 is 49.7 ps. A BER test with embedded PRBS checker inside a Xilinx 7 FPGA was also performed. An error free running of three days has been achieved, which corresponds to a BER less than 1 E-15. |  |
