Description

A Compton camera is presently under construction in Garching, aiming to allow for monitoring the ion-beam range and activity distribution from ion-beam irradiations of bio-medical samples via position-resolved prompt γ-ray detection. The Compton camera consists of a stack of six double-sided Si-strip detectors (50 x 50 mm2, 0.5 mm thick, pitch 390 μm) acting as scatterers, while the absorber is formed by a LaBr3 scintillator crystal (50§ x 50 x 30 mm3), read out by a multi-anode PMT. Results from characterization measurements are presented, covering energy, time, and spatial resolution. In order to characterize the position resolution, a strong and collimated 137Cs source (662 keV) was used to scan the 8 x 8 PMT pixel structure of the crystal.
