mm x 1.4 mm x 4.5 mmのLu2(1-x)Y2xSiO5結晶素子を32 x 8に配列し４層に重ね合わせた結晶ブロックと、256ch位置弁別型光電子増倍管をシリコンゴムによって光学結合させたものから成る。各プロトタイプ検出器からの256アノードの出力信号は、抵抗に繋ぐことで5出力まで減らされる。出力信号はPosition Analyzer回路によってデジタル化され、グルーピング回路、同時計数回路を通る。そして、点線源などの計測実験を行うことによって基礎性能を評価した。なお本研究の一部は、島津科学技術振興財団および平成17度科学研究費補助金若手研究B　(課題番号17700418)の助成を受けて行われた。厚く御礼申し上げる。","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名,
