Glitch effects in ISOCAM long wave detector

One of the main limitations to the sensitivity of observations carried out with the ISOCAM infrared camera comes from the responsivity variations and glitches caused by impacts of charged particles. After more than 28 months of successful operations, the predicted glitch rate has been re-evaluated a nd compared to in-flight measurements. Glitch properties have been studied in order to improve the removal algorithms, and thus the ultimate sensitivi ty of ISOCAM. All informations about the glitch phenomenon are very useful in order to prepare next space experiments.
