Abstract: (IOP)
For the upcoming high-luminosity LHC, the endcap calorimeters of the CMS experiment will be replaced by the high granularity calorimeter (HGCAL), a sampling calorimeter using both silicon and scintillator as active materials in different regions depending on the radiation dose. This contribution describes the integration details of the scintillator-based front-end into the readout chain of HGCAL.A prototype of the SiPM-on-tile readout chain was successfully operated in two recent beam tests at CERN SPS, demonstrating stable operation in a 3 T magnetic field and synchronization of sensor modules across different optical links.For the first time, both the silicon and SiPM-on-tile sensors of HGCAL are integrated into a single system utilizing a Serenity-Z FPGA card. Coarse event data which would be used for trigger logic are read out synchronously for both sensor types and across multiple layers.- Data acquisition circuits
