公募研究 広範な屈折率領域における高透明度シリカエアロゲルの開発（河合秀幸、千葉大） ＬＨＣ最前方での放射線環境測定とＧＳＯ輝度モニタの実証（さこ隆志、名古屋大） 離れた測定器読みだし回路とＣＯＰＰＥＲを結ぶ標準データ転送リンクの開発（伊藤領介、KEK）
Aerogel Radiator Developed by collaboration w/ Matsushita. Hydrophobic for long term stability 2005: Improved transmission by new recipie. 2008: New method (pin-hole drying) for higher index.
Backward f measurement at LEPS with TOP Backward f at LEPS with TOP Forward f at LEPS peak structure. proton K+,K- out of dipole TOP Dipole DC g Better K/p separation power than TPC in LEPS. Detect proton by forward spectrometer. Measure direction of K+K- with DC. Reconstruct momenta of KK using missing momentum of p(g,p)X Use TOP for K/p separation. (Most of Kaons don’t emit Cerenkov light.) For kaons with Cerenkov light, we can measure momenta using Cerenkov angle and mass of Kaon. Exotic hadron or exotic production mechanism?
