Description
The Forward Calorimeter (FoCal) is a new sub-detector for ALICE to be installed during CERN LS3, optimized for measurements in the forward region. FoCal-H, the hadronic calorimeter component of this upgrade, is designed as a scintillating-fiber calorimeter. Its front-end electronics are based on the H2GCROC ASIC, which was originally developed for the CMS HGCAL collaboration to read out SiPM signals. The ASIC has 72 channels and provides both energy and time information for the input signals. Key features like Time-over-Threshold (ToT) measurement and the current conveyor stage are important for efficient hadronic calorimeter readout.
In September, we tested the performance of H2GCROC with the FoCal-H prototype during a beam test at the SPS beamline. A fully customized hardware system based on the Xilinx KCU105 evaluation board, along with software built on the PySide framework, was used for the test. The results show that H2GCROC meets the demands of FoCal-H, confirming its capability for handling the front-end readout in the final detector.
