The ATLAS experiment at the CERN Large Hadron Collider: a description of the detector configuration for Run 3 / ATLAS Collaboration
The ATLAS detector is installed in its experimental cavern at Point 1 of the CERN Large Hadron Collider. During Run 2 of the LHC, a luminosity of $\mathcal{L}=2\times 10^{34}\mathrm{cm}^{-2}\mathrm{s}^{-1}$ was routinely achieved at the start of fills, twice the design luminosity. [...]

A readout digitization system for the ATLAS muon spectrometer phase-I tRPC trigger upgrade / Meng, X T (Lanzhou U. ; Michigan U.) ; Levin, D S (Michigan U.) ; Chapman, J W (Michigan U.) ; Li, D C (Lanzhou U.) ; Yao, Z E (Lanzhou U.) ; Zhou, B (Michigan U.)
The front-end digitization electronics for thin-Resistive Plate Chambers to be installed as part of the ATLAS Muon Spectrometer Phase-I upgrade project is described. The design is based on the CERN HPTDC and GOL chips. [...]

Fixed-latency gigabit serial links in a Xilinx FPGA for the upgrade of the muon spectrometer at the ATLAS experiment / Wang, Jinhong (Michigan U.) ; Hu, Xueye (Michigan U.) ; Pinkham, Reid (Michigan U.) ; Hou, Suen (Taiwan, Inst. Phys.) ; Schwarz, Thomas (Michigan U.) ; Zhu, Junjie (Michigan U.) ; Chapman, J W (Michigan U.) ; Zhou, Bing (Michigan U.)
We present an implementation of fixed-latency gigabit serial links in a low-cost Xilinx field-programmable gate array. The implementation is targeted for a data packet router in the upgrade of the ATLAS muon spectrometer. [...]

Latency study of the High Performance Time to Digital Converter for the ATLAS Muon Spectrometer trigger upgrade / Meng, X T (Lanzhou U. (main) ; Michigan U.) ; Levin, D S (Michigan U.) ; Chapman, J W (Michigan U.) ; Li, D C (Lanzhou U. (main)) ; Yao, Z E (Lanzhou U. (main)) ; Zhou, B (Michigan U.)
The High Performance Time to Digital Converter (HPTDC), a multi-channel ASIC designed by the CERN Microelectronics group, has been proposed for the digitization of the thin-Resistive Plate Chambers (tRPC) in the ATLAS Muon Spectrometer Phase-1 upgrade project. These chambers, to be staged for higher luminosity LHC operation, will increase trigger acceptance and reduce or eliminate the fake muon trigger rates in the barrel-endcap transition region, corresponding to pseudo-rapidity range 1<|η|<1.3. [...]

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. [...]

Design of a Trigger Data Serializer ASIC for the Upgrade of the ATLAS Forward Muon Spectrometer / Wang, Jinhong (Michigan U.) ; Guan, Liang (Michigan U.) ; Chapman, J.W. (Michigan U.) ; Zhou, Bing (Michigan U.) ; Zhu, Junjie (Michigan U.)
The small-strip Thin Gap Chamber (sTGC) will be used for both triggering and precision tracking purposes in the upgrade of the ATLAS forward muon spectrometer. Both sTGC pad and strip detectors are readout by a Trigger Data Serializer (TDS) ASIC in the trigger path. [...]

A Programmable Delay Design for the sTGC Detector at the Upgraded New Small Wheel of the ATLAS Muon Spectrometer / Wang, Jinhong (Michigan U.) ; Guan, Liang (Michigan U.) ; Chapman, John W (Michigan U.) ; Zhou, Bing (Michigan U.) ; Zhu, Junjie (Michigan U.)
We present a programmable time alignment scheme used in an ASIC for the ATLAS forward muon trigger development. The scheme utilizes regenerated clocks with programmable phases to compensate for the timing offsets introduced by different detector trace lengths. [...]

Simulation of the High Performance Time to Digital Converter for the ATLAS Muon Spectrometer trigger upgrade / Meng, X T (Lanzhou U. ; Michigan U.) ; Levin, D S (Michigan U.) ; Chapman, J W (Michigan U.) ; Zhou, B (Michigan U.)
The ATLAS Muon Spectrometer endcap thin-Resistive Plate Chamber trigger project compliments the New Small Wheel endcap Phase-1 upgrade for higher luminosity LHC operation. These new trigger chambers, located in a high rate region of ATLAS, will improve overall trigger acceptance and reduce the fake muon trigger incidence. [...]

FPGA Implementation of a Fixed Latency Scheme in a Signal Packet Router for the Upgrade of ATLAS Forward Muon Trigger Electronics / Wang, Jinhong (Michigan U.) ; Hu, Xueye (Michigan U.) ; Schwarz, Thomas (Michigan U.) ; Zhu, Junjie (Michigan U.) ; Chapman, J.W. (Michigan U.) ; Dai, Tiesheng (Michigan U.) ; Zhou, Bing (Michigan U.)
We propose a new fixed latency scheme for Xilinx gigabit transceivers that will be used in the upgrade of the ATLAS forward muon spectrometer at the Large Hadron Collider. The fixed latency scheme is implemented in a 4.8 Gbps link between a frontend data serializer ASIC and a packet router. [...]
