Abstract
The calorimeter Calocube is designed to bring a significant contribution to the direct observation of cosmic rays at high energy. This calorimeter will consist of scintillator (CsI(Tl)) cubes read out by photodiodes. In this report we present a study of the response of the front-end electronics of the Calocube prototype, that consists of 9 CASIS chips, coupled with the VTH2090 photodiode. The CASIS chip is a double-gain, large dynamic range Front-end ASIC for silicon detectors Read-Out. Thanks to some PSpice simulation, confirmed by measurements on the real circuit, we understood the causes of some anomalous behaviors of the front-end electronics that could disrupt the proper functioning of the prototype. We present also a few different circuit configurations that could partially eliminate this effects.
