Abstract :
The International Gamma-Ray Astrophysics Laboratory (INTEGRAL) soft gamma-ray imager (ISGRI) is the first large CdTe gamma camera ever built. It has provided faultless operations in space since the launch of INTEGRAL in October 2002. Here we give a general presentation of the system and pay particular attention to the noisy pixel handling. The observed effect of charged particles on the detectors and their integrated electronics is also presented. The in-flight detector evolution is detailed and the camera performance is reviewed
