第十二届中国 LHC 物理会议（CLHCP2026）

"Silicon microstrip detectors offer precise position measurements and a modular architecture for charged-particle tracking and beam diagnostics. This report presents the development and testing of lightweight, low-cost silicon microstrip systems for testbeam facilities and cosmic-ray detection, covering both an existing silicon beam monitor and a compact detector system currently under...

This work mainly covers the assembly of the UP Bare Stave and the design of the cooling system. The Bare Stave has undergone several design iterations, while the cooling system has been delivered to Hunan University and has passed preliminary testing.

The successful deployment of Monolithic Active Pixel Sensors (MAPS) in the Inner Tracking System 2 (ITS2) in the ALICE experiment at CERN, motivated the use of monolithic sensors in a 65 nm CMOS imaging process for the ALICE ITS3 upgrade and the ALICE 3 upgrade. The ITS3 upgrade aims to replace the three inner tracker layers during LHC Long Shutdown 3 (LS3) with ultra-thin, curved, wafer-scale...

"IHEP-USTC site is responsible for producing 44% of modules on HGTD. The IHEP-USTC site does module assembly through an automated Gantry System equipped with a vision system, glue dispenser, vacuum plates, and dedicated tools for precise pick-and-place of module components, hybrids, and module flexes.

An automatic workflow is being developed to efficiently handle the high module yield...

The High-Granularity Timing Detector (HGTD) is a key component of the ATLAS Phase-II upgrade for the HL-LHC. It employs Low-Gain Avalanche Detector (LGAD) sensors to provide precise timing measurement and mitigate pile-up effects in the forward detector region. This talk summarizes the latest production and quality control status of ATLAS HGTD LGAD sensors, including sensor batch...

Tencent/VooV Meeting: 817-821-557

The High-Granularity Timing Detector (HGTD) is a key component of the ATLAS Phase-II upgrade for the HL-LHC, employing Low-Gain Avalanche Detector (LGAD) sensors to provide precise timing and mitigate pile-up in the forward region. Each LGAD module is mounted on a dedicated Support Unit (SU) — 48 types of pure-PEEK structures, of which 839 are being fabricated. The SUs must hold the modules in...
