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…
Second generation of portable gamma camera based on Caliste CdTe hybrid technology
Daniel MAIER, Claire BLONDEL, Cyrille DELISLE +13
In the framework of a national funded program for nuclear safety, a first prototype of portable gamma camera was built and tested. It integrates a Caliste-HD CdTe-hybrid detector d…
Optimal X-ray filters for EDXRF analysis
Daniel Maier, Olivier Limousin, Diana Renaud +1
This work presents a semi-analytical approach to answer the question of optimal beam filtering in the case of EDXRF measurements with an X-ray tube. A collection of programs, calle…
Detection of polarized gamma-ray emission from the Crab nebula with Hitomi Soft Gamma-ray Detector
Hitomi Collaboration, Felix Aharonian, Hiroki Akamatsu +191
We present the results from the Hitomi Soft Gamma-ray Detector (SGD) observation of the Crab nebula. The main part of SGD is a Compton camera, which in addition to being a spectrom…
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…
