Abstract

Abstract The CMS High Granularity Calorimeter (HGCAL), developed for the High luminosity phase of the LHC (HL-LHC), uses custom ASICs — HGCROC3 and H2GCROC3 — to read out silicon sensors and SiPM-on-tile modules. These chips provide precise charge and timing measurements, digital processing for triggering, and are designed to operate in harsh radiation conditions. Version 3 of the chips implements all final features, with sub-versions a–d addressing bugs and improving radiation tolerance. Extensive testing has been performed in lab and beam environments. The proceedings covers chip design, performance, and SEE-related issues and fixes.
