1 Recap Analysis RIKEN/RBRC Itaru Nakagawa

2 Conductive Rubber Attempted to cut in RIKEN using super sonic cutter. Achieved Precision ~ ± 0.8mm 抵抗値 富士高分子 信越化学 EC-300BHEC-300BM 3x3x3 t mm ~1  ~80  ~40  カタログ 値 0.02  16  8 8 

3 Conductive Rubber Assembly Removed 2mm thick Fuji Polymer Made Conductive rubber and replaced with ShiEtsu EC-300BH. Silver paste glued Fuji Polymer’s rubber very well. Sticky enough for practical use for 2x2x2 t mm rubber. Not tested 3x3x3 t mm one yet. Silver paste glued Fuji Polymer’s rubber very well. Sticky enough for practical use for 2x2x2 t mm rubber.

16 Event Selection of Peak Strip Strip=21 fADC[][2]-fADC[][0]>1000 ある程度のタイミングセレクション は自動的に入って いる。 fADC[][2]>fADC[][3] を要求す るとイベントはなくなって しまう。つまり fADC[][2] でピークを 迎える事象はゴミイベントのみ。 ある程度のタイミングセレクション は自動的に入って いる。 fADC[][2]>fADC[][3] を要求す るとイベントはなくなって しまう。つまり fADC[][2] でピークを 迎える事象はゴミイベントのみ。
