Application of the VMM ASIC for SiPM-based calorimetry
View through CrossRef
Abstract
Highly integrated multichannel readout electronics is
crucial in contemporary particle physics experiments. A novel
silicon photomultiplier readout system based on the VMM3a ASIC was
developed, for the first time exploiting this chip for calorimetric
purposes. To extend the dynamic range the signal from each SiPM
channel was processed by two electronics channels with different
gain. A fully operational prototype system with 256 SiPM readout
channels allowed the collection of data from a prototype of the
ALICE Forward Hadron Calorimeter (FoCal-H Prototype 2). The design
and the test beam results using high energy hadron beams are
presented and discussed, confirming the applicability of VMM3a-based
solutions for energy measurements in a high rate environment.
