Introduction

The plots shown below have been approved by the NSW Project and may be shown by ATLAS speakers at conferences. Do not add plots on your own but contact the NSW project leader to arrange a plot approval.

Plot Approval Procedure

Plots and data concerning NSW detector performance, including test beam and/or module-0 results, can only be shown publicly if approved. Plots/results are approved by the NSW project leader after a discussion in the NSW Steering Group. Before requesting the approval of a plot, it should be presented, discussed and agreed on in the appropriate community, eg using the MicroMegas or sTGC Weekly meetings.

The official plot approval procedure is in place since October 2014, it was defined together with and endorsed by the Muon IB in its session on October 16 2014.

Public Plots

Fig. 1: Spatial resolution of a single Micromegas chamber vs incident angle Spatial resolution using the charge centroid method (blue triangles), the μTPC method (full red circles) and the combination of the two (black open circles)” as a function of the particle incident angle. The resolution is obtained from the residual distribution of the hit position difference between two Micromegas chambers separated by a small distance.

sTGC Performance

Public Plots

Fig. 2: Inclusive sTGC residual The reference track is built from all four hits in the sTGC quadruplet.
Fig. 2: Exclusive sTGC residual The reference track is built from three hits in the sTGC quadruplet, excluding the first hit for which the residual is computed.
Fig. 2: sTGC residual The reference track is built from hits in three pixel layers before and after the sTGC quadruplet.

Electronics

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.
