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

-- Junki Suzuki - 2016-08-17

8/17 19:33 Alignment start stage forward -> 10mm

-- Junki Suzuki - 2016-08-17

8/17 19:38 Alignment start stage forward -> 20mm

-- Junki Suzuki - 2016-08-17

8/17 20:00 Alignment start stage up -> 10mm

-- Atlasj Silicon - 2016-08-17

8/17 20:07 I_leak (43,35,45,0,0) [uA] @-58degC

-- Atlasj Silicon - 2016-08-17

8/17 20:19 Alignment start stage forward -> 40mm

-- Atlasj Silicon - 2016-08-17

8/17 20:27 Alignment start stage back -> 80mm

-- Atlasj Silicon - 2016-08-17

8/17 20:31 Alignment start stage down -> 30mm

-- Atlasj Silicon - 2016-08-17

8/17 20:56 HV OFF (KEK109,110,111)

-- Atlasj Silicon - 2016-08-17

8/17 21:12 Alignment stage down -> 40mm forward -> 40mm up -> 40mm forward -> 10mm back -> 20mm back -> 10mm forward -> 5mm

-- Junki Suzuki - 2016-08-17

8/18 0:30 increased temperature setpoint to 10 degrees

-- Atlasj Silicon - 2016-08-17

8/18 4:30 HV of KEK110 can only be increased up to about 30V. Started run with 0V.

-- Atlasj Silicon - 2016-08-18

for batch22(RJ2 run), moved the box 17mm "Down"

-- Atlasj Silicon - 2016-08-18

for batch23(RJ1 run), moved the box about 23mm "Backward" (Since there was a happening of moving the box too much Forward, the box stopped while moving. Don't know the exact position of box right now.)

-- Atlasj Silicon - 2016-08-18

No beam from around 7:20.
