| Outline of Final Research Achievements |
Utilizing the driving and signal processing electronics developed for the CCD camera onboard Hitomi satellite, we measured the response of the SDCCD (Scintillator-Deposited CCD) against hard X-rays at a synchrotron radiation facility of the High Energy Accelerator Research Organization (KEK). The device was cooled down to －70℃ and was irradiated with monochromatic X-rays from 30 to 80keV. The quantum efficiency as a function of energy agrees with that expected from the designed thicknesses of Si and CsI(Tl) of the SDCCD.
Radiation tolerance of the SDCCD was measured by irradiating the chip with protons (100 MeV/u). Radiation tolerance of the SDCCD is significantly better than those of the conventional CCDs, thanks to the additional implant below the gate electrodes and the resultant notch structure of the potential for the signal charges.
