Grand Park Otaru Hotel), Otaru, Hokkaido Japan, It is quite important to obtain wide band spectra of high energy astrophysical phenomena at the same time in order to probe emission processes or structures. Especially observations of transient objects, such as gamma-ray bursts of active galactic nuclei, expect detectors with wide energy band coverage for the sake of an efficient spectroscopy within limited time windows. An avalanche photo diode (APD) is a compact photon sensor with an internal gain of approximately 100. We have developed an X-ray / gamma-ray detector using a reach-through APD (5 × 5 sq mm) optically coupled with a conventional CsI(Tl) scintillator, which covers typically from 1 keV to 1 MeV. Further, we developed a 1-dimensional array of the 8/16 APDs (net 16 x 20) sq mm) for the purpose of an imaging photon detector combined with coded masks, to be applied in future missions. We present the current status and performances of our hybrid detector., 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: AA0064574172, レポート番号: JAXA-SP-09-008E}, pages = {440--441}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {Development of wide-band X-ray gamma-ray imagers using reach-through APD arrays}, volume = {JAXA-SP-09-008E}, year = {2010} }
