Simulation-based spectral analysis of X-ray CCD data affected by photon pile-up
Tsubasa Tamba, Hirokazu Odaka, Aya Bamba +6
We have developed a simulation-based method of spectral analysis for pile-up affected data of X-ray CCDs without any loss of photon statistics. As effects of the photon pile-up app…
Experimental studies on the charge transfer inefficiency of CCD developed for the soft X-ray imaging telescope Xtend aboard the XRISM satellite
Yoshiaki Kanemaru, Jin Sato, Toshiyuki Takaki +38
We present experimental studies on the charge transfer inefficiency (CTI) of charge-coupled device (CCD) developed for the soft X-ray imaging telescope, Xtend, aboard the XRISM sat…
Radiation hardness of a p-channel notch CCD developed for the X-ray CCD camera onboard the XRISM satellite
Yoshiaki Kanemaru, Jin Sato, Koji Mori +30
We report the radiation hardness of a p-channel CCD developed for the X-ray CCD camera onboard the XRISM satellite. This CCD has basically the same characteristics as the one used…
The FORCE mission : Science aim and instrument parameter for broadband X-ray imaging spectroscopy with good angular resolution
Kazuhiro Nakazawa, Koji Mori, Takeshi G. Tsuru +10
FORCE is a 1.2 tonnes small mission dedicated for wide-band fine-imaging x-ray observation. It covers from 1 to 80 keV with a good angular resolution of half-power-diameter.…
Soft X-ray Imager aboard Hitomi (ASTRO-H)
Takaaki Tanaka, Hiroyuki Uchida, Hiroshi Nakajima +25
The Soft X-ray Imager (SXI) is an imaging spectrometer using charge-coupled devices (CCDs) aboard the Hitomi X-ray observatory. The SXI sensor has four CCDs with an imaging area si…
In-orbit performance of the soft X-ray imaging system aboard Hitomi (ASTRO-H)
H. Nakajima, Y. Maeda, H. Uchida +46
We describe the in-orbit performance of the soft X-ray imaging system consisting of the Soft X-ray Telescope and the Soft X-ray Imager aboard Hitomi. Verification and calibration o…
