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…
Imaging and spectral performance of CdTe double-sided strip detectors for the Hard X-ray Imager onboard ASTRO-H
Kouichi Hagino, Hirokazu Odaka, Goro Sato +20
The imaging and spectral performance of CdTe double-sided strip detectors (CdTe-DSDs) was evaluated for the ASTRO-H mission. The charcterized CdTe-DSDs have a strip pitch of 0.25 m…
Modeling of proton-induced radioactivation background in hard X-ray telescopes: Geant4-based simulation and its demonstration by Hitomi's measurement in a low Earth orbit
Hirokazu Odaka, Makoto Asai, Kouichi Hagino +47
Hard X-ray astronomical observatories in orbit suffer from a significant amount of background due to radioactivation induced by cosmic-ray protons and/or geomagnetically trapped pr…
Suzaku spectra of a Type II Supernova Remnant Kes 79
Tamotsu Sato, Katsuji Koyama, Shiu-Hang Lee +1
This paper reports results of a Suzaku observation of the supernova remnant (SNR) Kes 79 (G33.6+0.1). The X-ray spectrum is best fitted by a two-temperature model: a non-equilibriu…
The Si/CdTe semiconductor Compton camera of the ASTRO-H Soft Gamma-ray Detector (SGD)
Shin Watanabe, Hiroyasu Tajima, Yasushi Fukazawa +23
The Soft Gamma-ray Detector (SGD) is one of the instrument payloads onboard ASTRO-H, and will cover a wide energy band (60--600 keV) at a background level 10 times better than inst…
