Reception test done and caps are glued to modules M1609-M1612.
M1611 graded B due to double column failure on ROC13. Others graded A. |

|
M1601-M1604 passed full test
M1601: grade B
M1602-M1604: Grade C. The main reason is failed pixels during trimbit test.

Wed Mar 18 15:23:27 2020, Andrey Starodumov, General, New rules at PSI
|
From today only two persons from the group allowed to be present. We are working in shifts: Urs in the morning start full qualification and I in the afternoon
test HDIs, run Reception, glue caps and switch the cold box, chiller etc after the full test finished.
Silvan is building usually 4 modules and 6-8 HDIs per day.

Wed Mar 18 15:16:47 2020, Andrey Starodumov, Software, Change in trimmig algorithm
|
Urs yesterday modified the algorithm and tested it. From today we are using it. Main change that threshold for trimming is not any more fixed to VthrComp=79
but calculated based on the bottom tornado value + 20. CalDel is also optimised. This allows us to avoid failures in the trimbit tests due to too high
threshold, eg if the bottom of tornado close to 70 a fraction of pixels in a chip could have threshold above 70 and hence fail in the test.

PhQualification was run on modules M1561, M1564, M1565, M1566. |
Mon Mar 16 15:17:18 2020, Matej Roguljic, Module assembly, M1601 and M1602

Andrey and I assembled modules 1601 and 1602 on Friday, 13.3. On Monday, 16.3. I ran reception on them (both graded A) and then glued protection caps on
them. |

I ran PhQualification over the weekend with changes pulled from git (described here https://elrond.irb.hr/elog/Layer+1+Replacement/108).

Mon Mar 16 10:05:23 2020, Matej Roguljic, Software, PhQualification change
|
Urs made a change in pXar, in the PhOptimization algorithm. One of the changes is in the testParameters.dat where vcalhigh is set to 100 instead of 255.
This was implemented on the PC used to run full qualification. A separate procedure for elComandante was created, "PhQualification.ini", which runs pretest,
pixelalive, trimming, ph and gainpedestal. This procedure will need to be run on all the modules qualified before this change was made and later merged |

|
I tested 5 HDIs on 12.3. 1030,1029,1040,1039 and 1038. 1039 failed all the electrical tests. All the others passed the tests. HDI 1038 has one wirebond
which is connected to the pad on the HDI and then it extends back up (like this: TBM./\.HDI/). The connection is good, but I just want to check with Silvan
later if this is a problem. |

Follow the instruction from M1591 regrading log:
"To correct the Summary page one needs to remove rows from DB with C grade from previous data analysis (that for some reason stayed in DB)

|
I tested 8 HDIs today: 5029,5030,5031,6034,6036,6035,1031 and 1032
All of them tested fine. |
Wed Mar 11 17:12:05 2020, Matej Roguljic, HDI test, HDI testing procedure change
|
There is an additional test that will be used from 11.03. on all HDIs. It involves measuring the voltage between ground and the HV pin of the needle card
with the goal of checking whether proper voltage is delivered to the HDI. The HDI testing script has been updated and it now prompts the user to set the
voltage to -800 V, measure the voltage on the pin and write this into the test results. After this, another instruction has been added which tells the |

|
Module M1586 had passed the full qualification on 20/02/27. I had had to re-insert the cable in the Molex connector for it to become programmable.
On 2020/03/09, I tried to re-test M1586, but it was not programmable. Visual inspection revealed nothing to me. I did re-insert the cable once again, but |

Tue Mar 3 14:05:13 2020, Andrey Starodumov, Re-grading, Regrading C modules: due to Noise
|
It has been realized by Urs that VCal to electron conversion used by MoreWeb is still 50e/VCal.
While recent calibration done by Maren with a few new modules suggest that this conversion is 43.7electrons per 1 VCal (the number from Danek).
I re-run MoreWeb analysis with 44e/Vcal for modules that are graded C for high noise (>300e).

Wed Mar 4 11:32:42 2020, danek kotlinski, Full test, change the target trim threshodl to vcal=50
|
After some discussion we decided to change the target trimming threshold from vcal 40 to 50.
Many ROCs cannot be run with xrays at 40 while all I have seen until now can be run at 50.
45 might be possible for some rocs but will fail for others.
