9:30 could not receive DACHS card at bld.6

(Because My name was not in the database.)

10:30 registered my name in the database at bld.6 room 208

11:30 received DACHS card

13:00 safety training(listen and sign name,no test)

14:00 setup

move last TB config file (ex.V2Sxx.json) to Sep2019_2 directory

make new connectivity config file:vendor6.json. and

install V6S04 /5. V6S05 is difficult to pass config. so exchange V6S05 to V6S03.

18:00 complete setup and checked digital/analog scan

install new version YarrEudaqProducer modified for memory leak problem. change the symbolic link of YarrEudaqProducerMulti from 201907xx to 20191126

apply voltage on V6S03 /4, the current is so high (-50V/100uA over)

the cuurent droped to 0 when apply some modules of vendor2 and vendor6 with connencting to YARR. (when extract display pot cable the problem did not occur)

try to connect PC GND and LV GND, PC GND and HV GND, but the problem did not resolved.

9:00 maybe the promble was due to Single Chip Card?

(1) module connect with only HV -> stable, 10(?)nA@-80V

(2) module connect with HV and DiplayPort -> unstable:often drop to 0 A

(3) module connect with HV and DisplayPort and LV power supply (ON) -> unstable

(4) module connect with HV and DisplayPort and LV (ON). LV GND and YARR GND short -> unstable

(5) module connect with HV and DisplayPort and LV (ON). HV GND and YARR GND short -> stable 20nA@-80V

jumper connecter whom name HV and GND added which (maybe) select short with HV and sensor, HV and LV. short sensor GND - HV GND - LV GND, and short YARR - LV GND.

--> stable current !!

re-setup

##run plan##

(1) full depletion voltage is different with vendor and ITk.

(2) tune different way:

1.target threshold:1500, include ToT tuning

2.target threshold:1500, NOT including ToT tuning for disappearing living analog core pattern.

3. target threshold:1000, ???

11:00?? tune V6S02 : first target:2000, second target:1500, injection:10000, ToT:7, including ToT tuning

11:30 tune V6S04 : same parameters.

14:00 run control PC setup especcially editing config files. work DAQ PC from runControlPC.

14:30 first beam out

15:30 modify the stage for beam hitting sensor of RD53A as looking the monitor.

17:00 run start : DUT0:V6S02, DUT1:V6S04, both-130V, 1500e, ToT tuning ON, 10M events
