A Prototype Si/CdTe Compton Camera and the Polarization Measurement
Takefumi Mitani, Takaaki Tanaka, Kazuhiro Nakazawa +7
A Compton camera is the most promising approach for gamma-ray detection in the energy region from several hundred keV to MeV, especially for application in high energy astrophysics…
Development of a Si/CdTe semiconductor Compton telescope
Takaaki Tanaka, Takefumi Mitani, Shin Watanabe +10
We are developing a Compton telescope based on high resolution Si and CdTe imaging devices in order to obtain a high sensitivity astrophysical observation in sub-MeV gamma-ray regi…
Development of Uniform CdTe Pixel Detectors Based on Caltech ASIC
K. Oonuki, H. Inoue, K. Nakazawa +6
We have developed a large CdTe pixel detector with dimensions of 23.7 x 13.0 mm and a pixel size of 448 x 448 um^2. The detector is based on recent technologies of an uniform CdTe…
Gamma-ray Polarimetry with Compton Telescope
Hiroyasu Tajima, Grzegorz Madejski, Takefumi Mitani +10
Compton telescope is a promising technology to achieve very high sensitivity in the soft gamma-ray band (0.1-10 MeV) by utilizing Compton kinematics. Compton kinematics also enable…
