Oral

Silicon pixel modules developed for the Phase2 CMS Inner Tracker were tested at HiRadMat facility, CERN, to evaluate potential damage in case of accidental beam loss at HL-LHC. Four pixel modules equipped with RD53 CROCv2 ASIC were exposed to fast and high intensity pulses of 440 GeV protons from SPS. The intensity of pulses was increased step-by-step: single bunch with increasing intensity up...

The Silicon Tracking System (STS) of the CBM experiment at FAIR requires a compact, high throughput readout architecture capable of operating at interaction rates up to 10 MHz. The STS Readout Board (STS-ROB), based on GBTx ASICs and Versatile Link optical interfaces, implements the data aggregation stage between front-end electronics and the back-end data acquisition system. The final...

Abstract —
A mass-production tester was developed for the RPC DCT boards of the ATLAS Phase-II upgrade, covering both legacy BM/BO and new BI detector variants. The system validates complete board functionality during prototype, pre-production, and forthcoming production phases. It emulates the RPC Sector Logic interface and 288 front-end hit inputs using representative 1 MHz, 12.5 ns pulses....

127. Wafer-Level Testing Challenges for ALTIROC-A ASICs in the ATLAS HGTD: Performance and Quality Control

Oral

ALTIROC-A is the front-end readout ASIC of the ATLAS High-Granularity Timing Detector (HGTD). Its large-scale production requires reliable wafer-level screening before dicing and module assembly. This contribution presents the ALTIROC-A wafer probing campaign, focusing on measured performance, including TDC and jitter characterization, wafer-to-wafer yield spread, and the constraints relevant...

198. HL-LHC upgrade of the CMS Experiment: Performance and Quality Control of the Inner Tracker Pixel Modules

Oral

The High-Luminosity LHC(HL-LHC) will reach instantaneous luminosities
up to $7.5\times10^{34},cm^{-2}s^{-1}$. The CMS Inner Tracker will be replaced to handle higher data rates, increased radiation, and finer
granularity. The new Inner Tracker(IT) uses hybrid modules based on RD53 65nm CMOS ASICs, bump-bonded to silicon sensors with a pixel size of $25\times100,\mu\text{m}$ and operated in...

ALFE2 is a front-end ASIC designed for the ATLAS Liquid Argon Calorimeter (LAr) in the High-Luminosity Large Hadron Collider (HL-LHC) upgrade. It integrates four channels of preamplifiers and shapers, each with two distinct gain outputs that can be read out in parallel to cover a 16-bit dynamic range. Over 80,000 chips have been fabricated in a 130 nm CMOS process. A robotic system performs...
