Verification of the Timing System for the X-ray Imaging and Spectroscopy Mission in the GPS Unsynchronized Mode
Megumi Shidatsu, Yukikatsu Terada, Takashi Kominato +59
We report the results from the ground and on-orbit verifications of the XRISM timing system when the satellite clock is not synchronized to the GPS time. In this case, the time is…
Development of the Timing System for the X-Ray Imaging and Spectroscopy Mission
Yukikatsu Terada, Megumi Shidatsu, Makoto Sawada +62
This paper describes the development, design, ground verification, and in-orbit verification, performance measurement, and calibration of the timing system for the X-Ray Imaging an…
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…
A concept for the X-ray telescope system with an angular-resolution booster
Yoshitomo Maeda, Ryo Iizuka, Takayuki Hayashi +7
We present a concept of the X-ray imaging system with high angular-resolution and moderate sensitivity. In this concept, a two-dimensional detector, i.e., imager, is put at a sligh…
In-flight performance of the Canadian Astro-H Metrology System
Luigi C. Gallo, Alexander Koujelev, Stephane Gagnon +11
The Canadian Astro-H Metrology System (CAMS) on the Hitomi X-ray satellite is a laser alignment system that measures the lateral displacement (X/Y) of the extensible optical bench…
Inorbit Performance of the Hard X-ray Telescope (HXT) on board the Hitomi (ASTRO-H) satellite
H. Matsumoto, H. Awaki, M. Ishida +16
Hitomi (ASTRO-H) carries two Hard X-ray Telescopes (HXTs) that can focus X-rays up to 80 keV. Combined with the Hard X-ray Imagers (HXIs) that detect the focused X-rays, imaging sp…
In-flight Calibration of Hitomi Soft X-ray Spectrometer (3) Effective Area
Masahiro Tsujimoto, Takashi Okajima, Megan E. Eckart +14
We present the result of the in-flight calibration of the effective area of the Soft X-ray Spectrometer (SXS) onboard the Hitomi X-ray satellite using an observation of the Crab ne…
Inflight Calibration of the Hitomi Soft X-ray Spectrometer (2) Point Spread Function
Yoshitomo Maeda, Toshiki Sato, Takayuki Hayashi +14
We present results of inflight calibration of the point spread function (PSF) of the Soft X-ray Telescope (SXT-S) that focuses X-ray onto the pixel array of the Soft X-ray Spectrom…
In-orbit performance of the soft X-ray imaging system aboard Hitomi (ASTRO-H)
H. Nakajima, Y. Maeda, H. Uchida +46
We describe the in-orbit performance of the soft X-ray imaging system consisting of the Soft X-ray Telescope and the Soft X-ray Imager aboard Hitomi. Verification and calibration o…
The ASTRO-H X-ray Astronomy Satellite
Tadayuki Takahashi, Kazuhisa Mitsuda, Richard Kelley +250
The joint JAXA/NASA ASTRO-H mission is the sixth in a series of highly successful X-ray missions developed by the Institute of Space and Astronautical Science (ISAS), with a planne…
