第 147 回土曜定例会(2002 年 6 月 15 日 - CNS) 村上、本林、下浦、栗田、Kalinka, Fulop, Elekes, 黒川、武内、齋藤、杉本、 五味、菅野、長谷川、出道 1. EXP199X解析   15O coulex (山田)    target excitation yield の精度向上   14Be -> 8He + 6He, 6He + 6He, 16Be (斎藤)    non-correlated events - improved statistics 2. 実験計画、開発   DALI-II - CsI (Elekes, Kalinka, 斎藤、柳澤 ...)    CsI-PD performance      PD - Hamamatsu 3590-01/08: eff. +5% for "08" (+10% in the Catalogue)      gluing: effects of bubbles      alignment: should be accurate      choice of glue: Epoxy - Epotek302 / Eccobond24?       Silicone (1 component) - DE777 Toray /       Dow Corning 732 / Tosseal78 / IS5675 (GE)       Silicone (2 component) - KE103 / RTV615       * long term stability / strength / optical property       stability tests: at 60 deg. (Tosseal78, Epotek302, KE-103)         => increase of light after 40min. / then decrease       reflective index: (1.8 for CsI, 1.5 for PD window)         1.56 for Epotek, 1.4-1.47 for silicon glue      CsI surface:       front surface - 3M foil / Al-Mylar (15% lower light yield than 3M)       side surface - Teflon + polished / 3M + mat       best: 3M (front) + 3M+mat (side - 2 3M layers are enough f. max.)      position dependence - 3M cap with holes       higher light yield in the corner / almost uniform for major part   DALI-II - NaI (出道、武内...)    Rikkyo version: Rikkyo => RIKEN (E6): 10 July ?   23Al、27P breakup (五味)    meeting: Monday 17    36Ar energy: 95 => 115 MeV/nucleon      yield, purity - improved <= simulation (Sugimoto)    silicon telescope      each layer: tested => test with 4 layers (E4 room)      geometry: determined relative to the chamber flange 3. 論文など   12N(峯村) - 進行中   13O(峯村) - 進行中   15O(山田) - 進行中   Ge 波形分析(黒川)   9C - もう二息で止まっている(本林)    M1 coulex が見えているかもしれない
