SUIM project: measuring the upper atmosphere from the ISS by observations of the CXB transmitted through the Earth rim
Kumiko K. Nobukawa, Ayaki Takeda, Satoru Katsuda +16
The upper atmosphere at the altitude of 60-110 km, the mesosphere and lower thermosphere (MLT), has the least observational data of all atmospheres due to the difficulties of in-si…
Xtend, the Soft X-ray Imaging Telescope for the X-ray Imaging and Spectroscopy Mission (XRISM)
Koji Mori, Hiroshi Tomida, Hiroshi Nakajima +52
Xtend is a soft X-ray imaging telescope developed for the X-Ray Imaging and Spectroscopy Mission (XRISM). XRISM is scheduled to be launched in the Japanese fiscal year 2022. Xtend…
Single Event Tolerance of X-ray SOI Pixel Sensors
Kouichi Hagino, Mitsuki Hayashida, Takayoshi Kohmura +19
We evaluate the single event tolerance of the X-ray silicon-on-insulator (SOI) pixel sensor named XRPIX, developed for the future X-ray astronomical satellite FORCE. In this work,…
X-ray Radiation Damage Effects on Double-SOI Pixel Detectors for the Future Astronomical Satellite "FORCE"
Masatoshi Kitajima, Kouichi Hagino, Takayoshi Kohmura +20
We have been developing the monolithic active pixel detector "XRPIX" onboard the future X-ray astronomical satellite "FORCE". XRPIX is composed of CMOS pixel circuits, SiO2 insulat…
Proton radiation hardness of X-ray SOI pixel sensors with pinned depleted diode structure
Mitsuki Hayashida, Kouichi Hagino, Takayoshi Kohmura +19
X-ray SOI pixel sensors, "XRPIX", are being developed for the next-generation X-ray astronomical satellite, "FORCE". The XRPIX are fabricated with the SOI technology, which makes i…
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…
