In run 4 of the LHC, the extreme high luminosity is expected to generate an enormous pileup of up to 200 proton-proton collisions for each bunch crossing. This has to be read out at 750 kHz with a maximum latency of 12.5𝜇s. In order to disentangle the energy from pileup collision, the upgraded CMS detector for Run-4 will feature a new High Granularity Calorimeter (HGCAL) with unprecedented lateral and longitudinal segmentation. The total number of channels read out into the Level-1 triggerdoi:10.5281/zenodo.3550706 fatcat:eqjsd6tkijelrdv6of364emnyu
