Performance evaluation of pnCCD onboard HiZ-GUNDAM mission

Abstract
We are developing a wide-field X-ray monitor onboard the HiZ-GUNDAM mission, which is a future satellite mission for observing gamma-ray bursts. The pnCCD detectors will be used as a focal plane detector. pnCCD has high sensitivity to low-energy X-rays and can achieve a high frame rate using column-parallel readout nodes. The performance evaluation of pnCCD detectors of a small-sized device will be reported for low-energy X-rays (0.4-4 keV) at a relatively high operating temperature of around -20 degrees Celsius.

I received a degree from Osaka University, worked at JAXA, RIKEN, and the University of Tokyo, and currently teach at Kwansei Gakuin University. For many years, he has contributed to the development of CCDs for use in X-ray astronomical satellites. In particular, he is good at considering the signal generation process inside a CCD through evaluation experiments of X-ray response in photon measurement mode. So far, he has contributed to experiments related to mission-mounted elements such as XRISM and XMM-Newton, as well as experiments using SOIPIX and visible light CMOS image sensors
