Grand Park Otaru Hotel), Otaru, Hokkaido Japan, We have produced gas electron multiplier (GEM) ,which is one of the recently developed micro-pattern gas detector, using a laser etching technique since 2002. Our GEM was selected as a key device of the X-ray polarimetry mission, Gravity and Extreme Magnetism SMEX (GEMS). Since GEMS will be the first mission carrying RIKEN / SciEnergy GEM into Low Earth Orbit, we have evaluated the risks which impact the GEM in space. We carried out gain stability measurements, obtaining that the GEM had enough stable gain for space uses. We irradiated Fe ion beam to our GEM for studying robustness against discharges. Our GEM survived the 40-year equivalent beam irradiation., 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: AA0064574173, レポート番号: JAXA-SP-09-008E}, pages = {442--443}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {Development of Gas Electron Multipliers for the X-ray Polarimetry Mission GEMS}, volume = {JAXA-SP-09-008E}, year = {2010} }
