High count rate effects in event processing for XRISM/Resolve x-ray microcalorimeter: I. Ground test
Misaki Mizumoto, Tsubasa Tamba, Masahiro Tsujimoto +11
The spectroscopic performance of an X-ray microcalorimeter is compromised at high count rates. In this study, we utilize the Resolve X-ray microcalorimeter onboard the XRISM satell…
High count rate effects in event processing for XRISM/Resolve x-ray microcalorimeter
Misaki Mizumoto, Masahiro Tsujimoto, Renata S. Cumbee +11
The spectroscopic performance of x-ray instruments can be affected at high count rates. The effects and mitigation in the optical chain, such as x-ray attenuation filters or de-foc…
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…
Ground test results of the electromagnetic interference for the x-ray microcalorimeter onboard XRISM
Miki Kurihara, Masahiro Tsujimoto, Megan E. Eckart +7
Electromagnetic interference (EMI) for low-temperature detectors is a serious concern in many missions. We investigate the EMI caused by the spacecraft components to the x-ray micr…
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…
