Prototype electronics for the silicon pad layers of the future Forward Calorimeter (FoCal) of the ALICE experiment at the LHC
View through CrossRef
Abstract
A Forward Calorimeter (FoCal) has been proposed as part of the ALICE upgrades for data
taking from 2029 onwards. The FoCal will feature a sampling electromagnetic calorimeter segmented
into 110 towers supplemented by a hadron calorimeter. The electromagnetic calorimeter will be
composed of 20 passive layers of tungsten absorber interleaved with 18 active layers of
low-granularity silicon pad sensors and two layers of high-granularity pixel detectors. Each pad
layer will be read out by 110 silicon pad sensors of 72 channels, amounting to a total of 1980
sensors.
This paper describes, from front-end to back-end, the electronics developed to instrument a tower
prototype composed of 18 silicon pad sensors as well as a design proposal for the full-detector
readout system.
