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., Meeting sponsors: The University of Tokyo, The Institute of Physical and Chemical Research, The Japan Society for the Promotion of Science, 資料番号: AA0064574162, レポート番号: JAXA-SP-09-008E}, pages = {420--421}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {Wide-band soft gamma-ray all-sky monitor by the large-area BGO active shield of the ASTRO-H Soft Gamma-ray Detector (SGD)}, volume = {JAXA-SP-09-008E}, year = {2010} }
