Development of soft x-ray CMOS camera for the GEO-X mission

We report on the development status of the CMOS camera to be installed in GEO-X. We have evaluated the spectral performance of the sensor by irradiating it with polychromatic X-rays. The energy resolution is found to be 120 eV (FWHM) at 0.6 keV and the lower edge of the effective energy range is below 300 eV. The fabrication of the printed circuit boards for housekeeping data collection is ongoing. We performed functional testing of a digital processing board using SoC (Zynq) and its radiation tolerance investigation. We also report the latest schedule for the FM camera and end-to-end test.
