Abstract
The IBIS telescope is a high angular resolution gamma-ray imager due to be launched on the INTEGRAL satellite on October 17, 2002. The scientific goal of IBIS is to study astrophysical processes from celestial sources and diffuse regions in the hard X-ray and soft gamma-ray domains. IBIS features a coded aperture imaging system and a novel large area (∼3000 cm2) multilayer pixellated detector which utilises both cadmium telluride (16,384 detectors) and caesium iodide elements (4096 detectors) surrounded by a BGO active veto shield. We present an overview of, and preliminary analysis from, the IBIS calibration campaign. The performance of each pixel has been characterised, and hence the scientific performance of the IBIS detector system as a whole can now be established. [Copyright &y& Elsevier]
