Multi-Image X-ray Interferometer Module: I. design concept and proof-of-concept experiments with fine-pitch slits
Kazunori Asakura, Kiyoshi Hayashida, Tomoki Kawabata +7
We propose a novel x-ray imaging system, Multi-Image X-ray Interferometer Module (MIXIM), with which a very high angular resolution can be achieved even with a small system size. M…
Ground test results of the micro-vibration interference for the x-ray microcalorimeter onboard XRISM
Takashi Hasebe, Ryuta Imamura, Masahiro Tsujimoto +8
Resolve is a payload hosting an X-ray microcalorimeter detector operated at 50 mK in the X-Ray Imaging and Spectroscopy Mission (XRISM). It is currently under development as part o…
Mechanical cryocooler noise observed in the ground testing of the Resolve X-ray microcalorimeter onboard XRISM
R. Imamura, H. Awaki, M. Tsujimoto +5
Low-temperature detectors often use mechanical coolers as part of the cooling chain in order to reach sub-Kelvin operating temperatures. The microphonics noise caused by the mechan…
The design and performance of the XL-Calibur anticoincidence shield
N. K. Iyer, M. Kiss, M. Pearce +31
The XL-Calibur balloon-borne hard X-ray polarimetry mission comprises a Compton-scattering polarimeter placed at the focal point of an X-ray mirror. The polarimeter is housed withi…
XL-Calibur -- a second-generation balloon-borne hard X-ray polarimetry mission
Q. Abarr, H. Awaki, M. G. Baring +38
XL-Calibur is a hard X-ray (15-80 keV) polarimetry mission operating from a stabilised balloon-borne platform in the stratosphere. It builds on heritage from the X-Calibur mission,…
X-ray imaging polarimetry with a 2.5-m pixel CMOS sensor for visible light at room temperature
Kazunori Asakura, Kiyoshi Hayashida, Takashi Hanasaka +9
X-ray polarimetry in astronomy has not been exploited well, despite its importance. The recent innovation of instruments is changing this situation. We focus on a complementary MOS…
