GARFIELD + RCo Digital Upgrade: a Modern Set-up for Mass and Charge Identification of Heavy Ion Reaction Products

摘要

An upgraded GARFIELD + Ring Counter (RCo) apparatus is presented withimproved performances as far as electronics and detectors are concerned. On oneside fast sampling digital read out has been extended to all detectors,allowing for an important simplification of the signal processing chaintogether with an enriched extracted information. On the other side a relevantimprovement has been made in the forward part of the setup (RCo): an increasedgranularity of the CsI(Tl) crystals and a higher homogeneity in the silicondetector resistivity. The renewed performances of the GARFIELD + RCo array makeit suitable for nuclear reaction measurements both with stable and withRadioactive Ion Beams (RIB), like the ones foreseen for the SPES facility,where the Physics of Isospin can be studied.
