Wide-band soft gamma-ray all-sky monitor by the large-area BGO active shield of the ASTRO-H Soft Gamma-ray Detector (SGD) 花畑, 義隆 山岡, 和貴 深沢, 泰司 Hanabata, Yoshitaka Yamaoka, Kazutaka Fukazawa, Yasushi ASTRO-H/SGD team Detector: Soft gamma-ray, Gamma-ray bursts The 3rd Suzaku international Conference "Energetic Cosmos : from Suzaku to ASTRO-H" (June 29-July 2, 2009. Grand Park Otaru Hotel), Otaru, Hokkaido Japan The SGD (Soft Gamma-ray Detector) is one of scientific instruments onboard the ASTRO-H. The main part of the SGD is Compton camera with a narrow field of view, surrounded by BGO active shileds. By this combination, SGD can achieve more than ten times as good a sensitivity as the Suzaku HXD (Hard X-ray Detecor). As well as the Suzaku HXD-WAM, BGO active shield can be operated as Wide-band All-sky Monitor (WAM) with a large effective area in 30 keV - 10 MeV energy band, to observe transient phenomena such as gamma-ray bursts (GRBs), soft gamma-ray repeaters (SGR), terrestrial gamma-ray flash (TGFs), and solar flares, and monitor bright soft gamma-ray sources with the earth occultation technique. Here, we present a design plan of soft gamma-ray monitor by SGD BGO active shiled and a current staus of development.
