Breadboard model of the SIDRA instrument designed for the measurement of charged particle fluxes in space

Abstract

This report delves into the concept of the SIDRA instrument designed for the measurement of energetic fluxes of charged particles in space. It also presents the preliminary laboratory tests results of the breadboard model electronic units. The SIDRA instrument consists of a detector head made of high purity silicon and high performance scintillation detectors, analog and digital signal processing units, and it also includes a secondary power supply module. Preliminary results of Monte Carlo instrument simulation using the CERN GEANT4 tool are presented and the measured key specifications of charge-to-voltage converters, shapers and peak detectors are discussed. Finally, the performance of the digital processing unit with its software and the parameters of the instrument breadboard model, in particular mass, dimensions and power consumption are also presented.
