Design and testing of an sTGC ASIC interface board for the ATLAS New Small Wheel upgrade
/ Wang, Xu (CUST, SKLPDE ; Hefei, CUST ; Michigan U.) ; Guan, Liang (Michigan U.) ; Sun, Siyuan (Michigan U.) ; Zhou, Bing (Michigan U.) ; Zhu, Junjie (Michigan U.) ; Jin, Ge (CUST, SKLPDE ; Hefei, CUST)
The ATLAS experiment will replace the present Small Wheel (SW) detector with a New Small Wheel detector (NSW) aiming to improve the performance of muon triggering and precision tracking in the endcap region at the High-Luminosity LHC. Small-strip Thin Gap Chamber (sTGC) is one of the two new detector technologies used in this upgrade. [...]

This paper describes the small-diameter monitored drift-tube detector construction at the University of Michigan as a contribution to the ATLAS Muon Spectrometer upgrade for the high-luminosity Large Hadron Collider at CERN. Measurements of the first 30 chambers built at Michigan show that the drift tube wire position accuracy meets the specification of 20 microns. [...]

Development of a time-to-digital converter ASIC for the upgrade of the ATLAS Monitored Drift Tube detector
/ Wang, Jinhong (Michigan U.) ; Liang, Yu (Hefei, CUST ; Michigan U.) ; Xiao, Xiong (Michigan U.) ; An, Qi (Hefei, CUST) ; Chapman, John W. (Michigan U.) ; Dai, Tiesheng (Michigan U.) ; Zhou, Bing (Michigan U.) ; Zhu, Junjie (Michigan U.) ; Zhao, Lei (Hefei, CUST)
The upgrade of the ATLAS muon spectrometer for high-luminosity LHC requires new trigger and readout electronics for the various elements of the detector. We present the design of a time-to-digital converter (TDC) ASIC prototype for the ATLAS Monitored Drift Tube (MDT) detector. [...]

The New Small Wheel electronics

The increase in luminosity, and consequent higher backgrounds, of the LHC upgrades require improved rejection of fake tracks in the forward region of the ATLAS Muon Spectrometer. The New Small Wheel upgrade of the Muon Spectrometer aims to reduce the large background of fake triggers from track segments that are not originated from the interaction point. [...]

Following the Higgs particle discovery, the Large Hadron Collider complex will be upgraded in several phases allowing the luminosity to increase to $7 \times 10^{34}cm^{-2}s^{-1}$. In order to adapt the ATLAS detector to the higher luminosity environment after the upgrade, part of the ATLAS muon end-cap system, the Small Wheel, will be replaced by the New Small Wheel. [...]

Two optical data link data transmission Application Specific Integrated Circuits (ASICs), the baseline and its backup, have been designed for the ATLAS Liquid Argon (LAr) Calorimeter Phase-I trigger upgrade. The latency of each ASIC and that of its corresponding receiver implemented in a back-end Field-Programmable Gate Array (FPGA) are critical specifications. [...]
