Imaging and Spectral Performance of a Wide-gap CdTe Double-Sided Strip Detector
Shunsaku Nagasawa, Takahiro Minami, Shin Watanabe +1
The fourth flight of the Focusing Optics X-ray Solar Imager sounding rocket experiment (FOXSI-4) aimed to achieve the first imaging spectroscopic observations of mid-to-large class…
FOXSI-2: Upgrades of the Focusing Optics X-ray Solar Imager for its Second Flight
Steven Christe, Lindsay Glesener, Camilo Buitrago-Casas +12
The Focusing Optics X-ray Solar Imager (FOXSI) sounding rocket payload flew for the second time on 2014 December 11. To enable direct Hard X-Ray (HXR) imaging spectroscopy, FOXSI m…
2-mm-Thick Large-Area CdTe Double-sided Strip Detectors for High-Resolution Spectroscopic Imaging of X-ray and Gamma-ray with Depth-Of-Interaction Sensing
Takahiro Minami, Miho Katsuragawa, Shunsaku Nagasawa +4
We developed a 2-mm-thick CdTe double-sided strip detector (CdTe-DSD) with a 250 um strip pitch, which has high spatial resolution with a uniform large imaging area of 10 cm an…
Wide-gap CdTe Strip Detectors for High-Resolution Imaging in Hard X-rays
Shunsaku Nagasawa, Takahiro Minami, Shin Watanabe +1
We propose a new strip configuration for CdTe X-ray detectors, named "Wide-gap CdTe strip detector", in which the gap between adjacent strips is much wider than the width of each s…
Detailed Design of the Science Operations for the XRISM mission
Yukikatsu Terada, Matt Holland, Michael Loewenstein +36
XRISM is an X-ray astronomical mission by the JAXA, NASA, ESA and other international participants, that is planned for launch in 2022 (Japanese fiscal year), to quickly restore hi…
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…
