Outline of Final Research Achievements

CCD camera is the standard detector in X-ray astronomy. The problem of the CCD camera is long exposure time of the frame. We cannot observe rapid variation of the X-ray objects with CCD cameras. The long exposure time also invoke another problem. If two or more X-ray photons irradiate narrow region, the X-ray events are mixed, and cannot be distinguished. To avoid these problem, we try new clocking method. During the exposure, several lines are transferred, and X-ray photons irradiate elongated region. We estimate the effectivity of new clocking mode. We also drive CCD camera with new clock, and confirm the availability of the mode.
