On Friday I have tested the module M1582 at room temperature in the blue box.
The report in MoreWeb says that this module has problems with trimming 190 pixels in ROC1.

M1562 was not qualified during a full test since the test did not complete.
Looking at the module I see that roc 2 has a lot of noise row 79.
I tried to mask all pixels in this row but the masking does not work.

There is no new PH optimisation for this module?!
To be checked! |

|
ROC10 of M1546 has 107 pixels with trimming problems:
in a VCal threshold scan after trimming 81 has a threshold underflow, means <0, and 26 pixels are outside 40-60VCal window (around Vcal 50) at +10C only.
Trimbit distribution looks reasonable.

I have tested M1542.
It looks not bad but there is a group of pixels in the lower/left corner of ROC6 which behave different.
One can also see that something is not right in some PH optimisation plots.

M1539 showed no readout. I tried, all without success,
- reconnecting the cable to the adapter multiple times
- connecting to the adapter in the blue box

|
After several attempts including reconnecting the cable, M1539 had no readout if it's connected to TB3. When connected to TB1, M1539 did not show any problem.
M1606 worked properly both with TB1 and TB3.
For FT test the configuration is following:

Wed Nov 20 16:53:50 2019, Andrey , Full test, M1533 and M1534 FullQualification
|
FullQualification of two modules M1533 and M1534 has been done. Full time of the test is about 7hrs.
Test included: FT@-10C, IV@-10, 2Cycles from -10C up to +10C, FT@-10C, IV@-10C, Ft@1-C and IV@10C.
No issues observed.

|
During an overnight (Feb. 4-5) FullQualification run with modules 1545, 1547, 1548, and 1549 the coldbox lost the ability to maintain the temperature at
-20 C. As can be seen from the attached temperature log, the problems already started during the temperature cycles where the last 2 cycles were noticeably
longer than the first 3 and finally during the second Fulltests at -20 C the temperature started rising and stabilized around -10 C. Based on these observations |

Here are HDIs that the first time tested showed 500-600V measured on the pin or directly on the HDI pad instead of 800V:
5006, 5007, 2005

|
We did some tests by running the latest version of pXar on modules M1521, M1529, M1534 and M1536, specifically trimming and PH optimization. Of the 4 modules
tested, the PH optimization converged only for M1521. We plan to further investigate with Urs' help possible reasons for failed PH optimization.

Thu Jan 23 14:54:45 2020, Dinko Ferencek, Cold box tests, Keithley exchanged
|
Yesterday during an attempt to run the FullQualification, elComandante would lose control over Keithley after performing the IV curve measurements and would
go in the subsequent Fulltest with HV off. This happened both between the two sets of tests at -20 C and between the tests at -20 C and +10 C. Today we
exchanged the old Keithley with a new one and we observe that the communication with this new Keithley is much smoother without any error codes and warning |

Thu Oct 31 10:41:12 2019, Matej Roguljic, Cold box tests, Issue with DTB_WWVASW
|
On 29th of October, an issue with DTB_WWVASW was noticed when trying to run FullQualification on 4 modules at the same time. On a tested, working module,
setting Vana works but taking tornado plots (setvthrcomp) doesn't as well as other tests. Curiously enough, after switching the DTB with the one used for
HDI testing (DTB_WRN13L) the problem was still there. This lead us to believe that the problem was with cables or ground. All cables and the adapter were |
