Towards a High-Performance Readout System for the CMS High Granularity Calorimeter — •Fabian Hummer, Luis Ardila, and Frank Simon — Karlsruhe Institute of Technology

For the upcoming high-luminosity LHC, the endcap calorimeters of the CMS experiment will be replaced by the high granularity calorimeter (HGCAL), one of the most ambitious detector projects undertaken. Due to the extremely high number of readout and trigger channels, in combination with a high event rate and pile-up, HGCAL requires a high-performance, FPGA-based readout system. Collaborating closely with CERN, DESY and Imperial College London, the CMS group at the Institute for Data Processing and Electronics (IPE) at KIT contributes both to development of firmware and software for the readout and control of HGCAL, as well as to the design of the new Serenity-S1 hardware. In this contribution I will discuss how we address the challenges in data readout that we are facing for HGCAL, and highlight the contributions from IPE at KIT.
