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

add jumper pin which select short with HV and bias ring. (near HV Lemo connector), and short with HV GND and bias ring.

--> 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

9:00 stack...

10:30 tune modules with -100V, NO ToT tuning. (other parameters are same)

debug 50x50 vendor6 modules, but cannot

15:45 tune V6S02 : DiffVff =1 and V6S04 : DiffVff =1 (default Vff=50) , No ToT tuning

16:00 tune V6S02 : DiffVff =30 and V6S04 : DiffVff =30 , No ToT tuning

16:10 tune V6S02 : DiffVff =50 and V6S04 : DiffVff =50 , No ToT tuning-> default Diffvff=50 and tuned Diffvff=50 were not result

16:15 did digital scan for return default , and made new configfile->but not 1500e (in fact near 1650e)

16:30 changed DUT0 100V and DUT1=100V -> double peak...

17:00 changed DUT0 130V and DUT1=129.8V ,1000e, tune V6S02 :DiffVff=50 and V6S04 =50 , No ToT tuning

28 Nov, 2019

afternoon :DUT0(V6S02) tuned 1500e ToT and DUT1(V6S04) removed jumpers for grownding

DUT0 changed 80V -> 100V -> 130V -> 50V -> 10V -> 30V ->130V each with 5M events

DUT1 changed 130V -> 100V -> 80V -> 50V -> 30V -> 10V each with 5M events
