8/15 Tuning & noise scan for (irradiated sensor) KEK109~111, (non-irradiated sensor) KEK112, and (reference plane) KEK82,83,94 ...done.

-- Atlasj Silicon - 2016-08-16

8/16 22:00~ Angle run alignment & daq start at H6B

-- Atlasj Silicon - 2016-08-16

8/17 16:00 threshold has changed. (by temperature ?) -> re-tune

-- Junki Suzuki - 2016-08-17

8/17 18:49 too many leakage current ~-200uA@-200V (KEK109,110,111) and current limit(HV line) does not work.

-- Junki Suzuki - 2016-08-17

8/17 19:00 module(KEK109,KEK110,KEK111,KEK112,KEK82) HV (200,200,200,50,300) [V] I_leak start (194,202,276,0,0) [uA]

-- Junki Suzuki - 2016-08-17

8/17 19:17 and_mask=7 ~4600 events/spill

-- Junki Suzuki - 2016-08-17

8/17 19:17 and_mask=3 ~7500 events/spill

-- Junki Suzuki - 2016-08-17

8/17 19:17 and_mask=12 ~2300 events/spill

-- Junki Suzuki - 2016-08-17

8/17 19:17 set "and_mask -> 3", run start
