Test 状況

[08 Feb.]

LV, HV用のケーブルを作成.

プラグの既製品型番

HV: https://jp.rs-online.com/web/p/pcb-connector-housings/4476754/
LV: https://www.phoenixcontact.com/online/portal/jp/?uri=pxc-oc-itemdetail:pid=1780529&library=jpja&pcck=P&tab=1&selectedCategory=ALL

[09 Feb.]

50D miniture diode Non-irrad. を乗せてTest開始.

Ampに乗せた状態でHVをかけるとLeakageが3桁程度去年の結果より大きい.

(光を入れてもcurrentの上昇は殆ど見られない).

[10 Feb.]

50CのMonitor Diodeをtest.

Laserで信号確認.

~1200mV ~20ns @-350V

β-sourceで信号確認.(trigger: プラスチックシンチ&PMT)

~2ns? ~20mV @-400V

50~100mV @-450V

~100mV @-500V

~150mV @-550V
