Abstract :
We are developing a new Anger camera for nuclear imaging in the framework of the HICAM (HIgh resolution CAMera) project supported by European Community. The camera is foreseen to be employed in applications where high-position resolution (~ 1 mm intrinsic spatial resolution) and camera compactness are of primary concern. The camera is based on the use of monolithic arrays of Silicon Drift Detectors (SDDs), each one with a JFET integrated in the detector chip. In this work we present the results of the characterization of a first prototype of the camera (1/4 of the final expected active area), composed by 25 SDDs of 1 cm2 each in a 5×5 format. The module is read-out by a single 25-channels ASIC. The prototype of the camera is presented in this work together with the results of the gamma-ray imaging characterization.
