5 Feb 2020 | | Abstract: | The motivation of the current R&D project is based upon the requirements of
the JEDI international collaboration aiming to measure Electric Dipole Moments
(EDMs) of charged particles in storage rings. One of the most important
elements of such an experiment will be a specially designed polarimeter with
the detection system based on a modular inorganic scintillator (LYSO crystal)
calorimeter. The calorimeter modules are read out by Silicon Photo Multipliers
(SiPMs). This paper describes the development of a multi-channel power supply
for the polarimeter modules, providing very stable and clean bias voltages for
SiPMs. In order to ensure the best possible performance of SiPMs in conjunction
with the crystal-based calorimeter modules and to guarantee the required level
of calorimeter stability, several quality requirements have to be met by the
power supply. Additionally, it is required to provide features including remote
control via the network, ramping of the output voltage, measuring and sending
the information about its output voltages and currents, etc. The obtained
results demonstrate that the goals for the JEDI polarimeter are met. The
developed hardware will be useful in other fields of fundamental and applied
research, medical diagnostic techniques and industry, where SiPMs are used. | | Source: | arXiv, 2002.1700 | | Services: | Forum | Review | PDF | Favorites | |
