Abstract

IBIS is the imaging telescope onboard the ESA satellite INTEGRAL. IBIS will produce images of the gamma-ray sky in the region between 15 keV and 10 MeV by means of a position sensitive detection plane coupled with a coded aperture mask. The detection plane comprises two position sensitive layers: ISGRI and PICsIT. PICsIT is a 64 X 64 unit array of approximately 0.75 cm² crystals operating in the energy range between 150 keV and 10 MeV, arranged as 8 modules of 512 pixels. The PICsIT Qualification Model consists of one module and is therefore fully representative of the scientific performances of the flight model in terms of gain, linearity lower energy threshold and energy resolution. The performances evaluated from the analysis of the module calibration data are presented.
