Detailed Description
Algorithm for digitizers of the Monte Carlo hits of Calo based on a preliminary Pd readout.
This algorithm converts the energy deposit in a LYSO cube from GeV obtained with the MC simulation to ADC, taking into account several parameter regarding the photodiodes (PD) and the front-end electronics. It is based on several laboratory test performed in 2019/2020 using the HIDRA chips, version 2. Each PD is connected to a dedicated HIDRA channel. The ACQ system is based on the TROC2-1 boards. Brief HIDRA description (see the data-sheet): "The HIDRA-2 ASIC includes 16 frontend channels, based on a pulsed reset Charge Sensitive Amplifier (CSA) with automatic double-gain selection, followed by a Correlated Double Sampling (CDS) filter, and a self-trigger circuitry that provides a differential CMOS output for each pair of channels".
