Atsushi Takada,Kaori Hattori,Hidetoshi Kubo,Kentaro Miuchi,Tsutomu Nagayoshi,H. Nishimura,Y. Okada,Reiko Orito,Hiroyuki Sekiya,A. Tada,Toru Tanimori +10 more
TL;DR: A prototype of the MeV gamma-ray imaging camera based on the full reconstruction of the Compton process has been developed in this paper, which consists of a micro-TPC that is a gaseous Time Projection Chamber (TPC) and scintillation cameras.
Journal ArticleDOI
Development of Electron Tracking Compton Camera using micro pixel gas chamber for medical imaging
Shigeto Kabuki,Kaori Hattori,Ryota Kohara,Etsuo Kunieda,Atsushi Kubo,Hidetoshi Kubo,Kentaro Miuchi,Tadaki Nakahara,Tsutomu Nagayoshi,H. Nishimura,Y. Okada,Reiko Orito,Hiroyuki Sekiya,Takashi Shirahata,Atsushi Takada,Toru Tanimori,Kazuki Ueno +16 more
TL;DR: The Electron Tracking Compton Camera (ETCC) as mentioned in this paper reconstructs the 3D tracks of the scattered electron in Compton process for both sub-MeV and MeV gamma rays.
Journal ArticleDOI
Direction-sensitive dark matter search results in a surface laboratory
Kentaro Miuchi,Kaori Hattori,Shigeto Kabuki,Hidetoshi Kubo,Shunsuke Kurosawa,H. Nishimura,Y. Okada,Atsushi Takada,Toru Tanimori,K. Tsuchiya,Kazuki Ueno,Hiroyuki Sekiya,Atsushi Takeda +12 more
TL;DR: In this paper, a three-dimensional gaseous tracking device and a direction-sensitive dark matter search were performed in a surface laboratory. And they obtained a sky map drawn with the recoil directions of the carbon and fluorine nuclei, and set the first limit on the spin-dependent WIMP (Weakly Interacting Massive Particles)-proton cross section by a direction sensitive method.
Journal ArticleDOI
A very large area Micro Pixel Chamber
Atsushi Takada,Kaori Hattori,Shigeto Kabuki,Hidetoshi Kubo,Kentaro Miuchi,T. Nagayoshi,H. Nishimura,Y. Okada,Reiko Orito,Hiroyuki Sekiya,Atsushi Takeda,Toru Tanimori,Kazuki Ueno +12 more
TL;DR: Tanimori et al. as discussed by the authors developed a new μ-PIC having a ∼ 30 × 30 cm 2 detection area, and the structure and the pitch of the electrode are the same as those of the previous one.
Journal ArticleDOI
Development of an ASD IC for the micro pixel chamber
Reiko Orito,Osamu Sasaki,Hidetoshi Kubo,Kentaro Miuchi,Tsutomu Nagayoshi,Y. Okada,Atsushi Takada,Atsushi Takeda,Toru Tanimori,M. Ueno +9 more
TL;DR: In this paper, a new amplifier-shaperdiscriminator (ASD) chip was designed and manufactured for the micro pixel chamber (/spl mu/-PIC) using SONY Analog Master Slice bipolar technology.
