Abstract
Hi-vision pictures taken aboard tne space shuttle have suffered from CCD white defects. Considering, therefore, that protons in space radiation may bethe cause of these white defects, the CCD used for taking High-vision pictures on the space shuttle (STS-95) was analyzed and a proton irradiation expriment wa performed on the ground. The results of this experiment revealed that protons gave grear effect on the occurrence of white dedfects.
