Origin of the in-orbit instrumental background of the Hard X-ray Imager onboard Hitomi
Kouichi Hagino, Hirokazu Odaka, Goro Sato +43
Understanding and reducing the in-orbit instrumental backgrounds are essential to achieving high sensitivity in hard X-ray astronomical observations. The observational data of the…
Low-Energy X-ray Performance of SOI Pixel Sensors for Astronomy, "XRPIX"
Ryota Kodama, Takeshi Go Tsuru, Takaaki Tanaka +17
We have been developing a new type of X-ray pixel sensors, "XRPIX", allowing us to perform imaging spectroscopy in the wide energy band of 1-20 keV for the future Japanese X-ray sa…
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…
Shock-Cloud Interaction in the Southwestern Rim of RX J1713.73946 Evidenced by Chandra X-ray Observations
Takaaki Tanaka, Hiroyuki Uchida, Hidetoshi Sano +1
We report on results of Chandra X-ray observations of the southwestern part of the supernova remnant (SNR) RX J1713.73946. We measure proper motions of two X-ray bright blobs, n…
Radiation Damage Effects on Double-SOI Pixel Sensors for X-ray Astronomy
Kouichi Hagino, Keigo Yarita, Kousuke Negishi +19
The X-ray SOI pixel sensor onboard the FORCE satellite will be placed in the low earth orbit and will consequently suffer from the radiation effects mainly caused by geomagneticall…
Optical Blocking Performance of CCDs Developed for the X-ray Astronomy Satellite XRISM
Hiroyuki Uchida, Takaaki Tanaka, Yuki Amano +43
We have been developing P-channel Charge-Coupled Devices (CCDs) for the upcoming X-ray Astronomy Satellite XRISM, planned to be launched in 2021. While the basic design of the CCD…
