The status of pnCCD with an FPGA-based electronic system for HiZ-GUNDAM

HiZ-GUNDAM is a proposed satellite mission for JAXA to promote time-domain and multi-messenger astronomy as the main targets of gamma-ray bursts. As the mission payload, the wide field X-ray monitors consist of a lobster eye optics array and a focal imaging sensor. The field of view of the monitor is ~0.7 steradian in the soft X-ray band (0.4 – 4 keV). As the X-ray detector, the pnCCD detector fabricated by PNSensor Inc. can achieve our mission requirements, and we are developing an FPGA-based electronic system for the pnCCD. Our bread-board model of the electronic system consists of (1) a FPGA board, (2) an ADC & driver board, (3) a Power supply board, and (4) a 96×192 pixel pnCCD read out by 4 CAMEX analog front-end ASICs. We have driven CAMEXs successfully by sending the test pulse. In this paper, we report the development status of pnCCD by our FPGA-based electronic system.
