The Si/CdTe semiconductor Compton camera of the ASTRO-H Soft Gamma-ray Detector (SGD)
Shin Watanabe, Hiroyasu Tajima, Yasushi Fukazawa +23
The Soft Gamma-ray Detector (SGD) is one of the instrument payloads onboard ASTRO-H, and will cover a wide energy band (60--600 keV) at a background level 10 times better than inst…
Development of the analog ASIC for multi-channel readout X-ray CCD camera
Hiroshi Nakajima, Daisuke Matsuura, Toshihiro Idehara +7
We report on the performance of an analog application-specific integrated circuit (ASIC) developed aiming for the front-end electronics of the X-ray CCDcamera system onboard the ne…
Development of an n-channel CCD, CCD-NeXT1, for Soft X-ray Imager onboard the NeXT satellite
Shin-ichiro Takagi, Takeshi Go Tsuru, Tatsuya Inui +10
NeXT (New X-ray Telescope) is the next Japanese X-ray astronomical satellite mission after the Suzaku satellite. NeXT aims to perform wide band imaging spectroscopy. Due to the suc…
Spectral evolution of GRB 060904A observed with Swift and Suzaku -- Possibility of Inefficient Electron Acceleration
Daisuke Yonetoku, Sachiko Tanabe, Toshio Murakami +39
We observed an X-ray afterglow of GRB 060904A with the Swift and Suzaku satellites. We found rapid spectral softening during both the prompt tail phase and the decline phase of an…
Performance of the Charge Injection Capability of Suzaku XIS
H. Nakajima, H. Yamaguchi, H. Matsumoto +17
A charge injection technique is applied to the X-ray CCD camera, XIS (X-ray Imaging Spectrometer) onboard Suzaku. The charge transfer inefficiency (CTI) in each CCD column (vertica…
