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…
IRDFF-II: A New Neutron Metrology Library
A. Trkov, P. J. Griffin, S. P. Simakov +21
High quality nuclear data is the most fundamental underpinning for all neutron metrology applications. This paper describes the release of version II of the International Reactor D…
In-orbit performance and calibration of the Hard X-ray Imager onboard Hitomi (ASTRO-H)
Kouichi Hagino, Kazuhiro Nakazawa, Goro Sato +37
The Hard X-ray Imager (HXI) onboard Hitomi (ASTRO-H) is an imaging spectrometer covering hard X-ray energies of 5-80 keV. Combined with the hard X-ray telescope, it enables imaging…
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…
Study of the Polarimetric Performance of a Si/CdTe Semiconductor Compton Camera for the Hitomi Satellite
Junichiro Katsuta, Ikumi Edahiro, Shin Watanabe +17
Gamma-ray polarization offers a unique probes into the geometry of the gamma-ray emission process in celestial objects. The Soft Gamma-ray Detector (SGD) onboard the X-ray observat…
The first demonstration of the concept of "narrow-FOV Si/CdTe semiconductor Compton camera"
Yuto Ichinohe, Yuusuke Uchida, Shin Watanabe +14
The Soft Gamma-ray Detector (SGD), to be deployed onboard the {\it ASTRO-H} satellite, has been developed to provide the highest sensitivity observations of celestial sources in th…
