Forward Array Using Silicon Technology


         FAUST is a forward array composed of 68 high resolution Si-CsI(Tl) telescopes mounted on 5 concentric rings. Each detector is composed of a 300microns silicon detector with a CsI(Tl) scintillator with light readout with a photodiode. The pre-ampliers for both Si and CsI(Tl) were mounted close to the detectors to minimize noise pickup and thus to ensure a good resolution. Those pre-amplifier and the accompanying amplifiers were designed here at Texas A&M.


The purpose of this device is to study the isospin dependence in projectile fragmentation.
