Abstract
The aim of this work is to present a 64-independent channels, low noise and wide dynamic range readout system for multi-anodes photo-multiplier tubes (MA-PMTs). The results consist of some imaging tests obtained with a Hamamatsu H8500 MA-PMT coupled to different scintillation crystals, like a LaBr(3)(Ce) continuous crystal and NaI(Tl), CsI(Tl) and YAP pixilated scintillation arrays. Moreover, the Hamamatsu H8500C-Mod8 new series equipped with a super bialkali (SBA) photocatode was also studied. Energy and spatial resolutions showed an improvement with respect to the previous generation of multi-channel read-out electronics and we also reported some very interesting results with LaBr(3)(Ce) crystal coupled to the new Hamamatsu H8500-Mod8 with high quantum efficiency. That demonstrated the excellent response characteristics and versatility of our proposed electronic system and its potential use with all gamma-ray detectors.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
