Description
Wide-field soft X-ray surveys are important for future gamma-ray burst observations. The HiZ-GUNDAM satellite will use lobster-eye optics and pnCCDs to observe soft X-ray transients such as gamma-ray bursts. In this study, the radiation tolerance of a small pnCCD with a pixel size of 75 µm and a depletion thickness of 450 µm was evaluated. In this test, radiation damage due to orbital total dose effect was given by 10 MeV proton beams as representative. As a result of performance evaluation after the test, the operating temperature and framerate range of the pnCCD required to meet the HiZ-GUNDAM mission requirement of 0.4 keV lower detectable energy was calculated.
