 Wed Mar 25 18:31:46 2020, Andrey Starodumov, Re-grading, Reanalised test results
|
[quote="Andrey Starodumov"]Test resulsts of several modules have been re-analised without grading on trimbit failure.
M1614: C->B
M1613: C->A
|
 Wed Mar 25 18:40:53 2020, Andrey Starodumov, Full test, FT of M1599, M1613, M1624, M1616
|
M1599: B due to leakage current at +10 (2-3umA)
M1613: B due to a few pixels with bad trimmed threshold
M1624: B due to a few ROCs with mean noise>200electrons

Thu Mar 26 17:41:52 2020, Andrey Starodumov, Reception test, RT of M1629-1632
|
| All modules M1629, M1630, M1631 and M1632 graded A |
|
Thu Mar 26 17:43:06 2020, Andrey Starodumov, HDI test, 6+1 HDI tested
|
HDIs: 6021, 3014, 2005, 2009, 2006 and 2010 are OK
HDI 6024 failed: SDA0 and SDA2 on Ch1 missing

|
Thu Mar 26 17:45:15 2020, Andrey Starodumov, Full test, FT of M1545, M1557, M1627, M1628
|
Retested M1545: C->B (to be correct on the MoreWeb summary page)
Retested 1557: C->C in one ROC >160 pixels failed to be trimmed [B]Module placed in a tray C*[/B]
1627: B
|
|
Fri Mar 27 14:28:14 2020, Andrey Starodumov, Reception test, M1633 failed Reception
|
All ROCs are programmable but permanent DESERALISER ERROR, Ch6 and Ch7 event ID mismatch.
Visual inspection is OK
To module doctor |

Fri Mar 27 14:32:11 2020, Andrey Starodumov, HDI test, List of suspicious HDIs
|
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
3014, 3017, 3019, 6021

|
Fri Mar 27 14:46:04 2020, Andrey Starodumov, Module doctor, Wolfram's summay from Mar 25
|
M1542 nothing on sdata3 (12-15), bad output or wire-bond
M1544 ROC15 timing off, can be made to work (roc 15 vdig 11, ..), but probably not usable for the detector
M1545 full readout, ok, upgraded to C*

|
All ROCs are programmable but DESER400 trailer error bits: "NO DATA" or "IDLE DATA".
ROC8-11 are affected (no data)
Visual inspection is OK
|
|
Fri Mar 27 18:28:34 2020, Andrey Starodumov, Full test, 4 HDIs tested
|
| HDIs 5020, 5018, 1044 and 1041 are OK |
|
Fri Mar 27 18:29:53 2020, Andrey Starodumov, Full test, FT of M1629, M1630, M1631, M1632
|
M1629: B due to mean noise at -20C
M1630: C due to ROC1 with all pixels failed of PH calibration (Gain). Both FT at -20C are A!
Should be understood and retested. Put in C* tray.

Mon Mar 30 16:46:59 2020, Andrey Starodumov, DB, Sensors missing in Advacam spreadsheet
|
Dinko noticed that several sensors are missing in Advacam spreadsheet:
- 381785-03-3 used for M1586
- 381783-02-1 used for M1617
|
|
Mon Mar 30 17:40:35 2020, Andrey Starodumov, HDI test, 3+2 HDIs (re-)tested
|
For 3 HDIs: 3014, 3017, 6021, HV has been re-measured. In all cases 790V is measured with 800V supplied.
2 HDIs: 1026, 5022 were tested. Both OK.
All 5 HDIs will be used in module assembly. |
|
Mon Mar 30 17:49:31 2020, Andrey Starodumov, Reception test, RT of M1637-1640
|
All modules: M1637, M1638, M1639, M1649, are graded A.
|
|
Tue Mar 31 08:21:39 2020, Andrey Starodumov, Full test, FT of 1558, 1606, 1634, 1636 on Mar 30
|
M1558: B
M1606: C again due to trimmed threshold for 189 pixels of ROC2 at -20C. Second time at -20C and at +10C the number of failed pixels is 90+, hence grading
is B.

Tue Mar 31 17:32:47 2020, Andrey Starodumov, Reception test, RT of M1641-M1644
|
| All modules graded A. |
|
Tue Mar 31 17:33:37 2020, Andrey Starodumov, Reception test, RT of M1546
|
This is a module with a broken TBM. Silvan put a new one on top of the broken TBM.
The module is graded A after reception test.
I'm still not sure that wire-bonds of the new TBM is lower than capacitors. I'll try to glue a cap tomorrow

|
Tue Mar 31 18:14:47 2020, Andrey Starodumov, HDI test, 3 HDI tested
|
| HDIs: 1027, 5002, 5003 are tested. All OK. |
|
Tue Mar 31 18:23:18 2020, Andrey Starodumov, Full test, FT of M1637, M1638, M1639, M1640
|
M1637: C. Graded C due to not completed first test at -20C. Urs has reported issues. The second -20C after T-Cycle and test at +10C are graded A.
Tomorrow I'll upgrade this module manually to A
M1638: A
