Anrey Starodumov | Full test | 4 modules FT: 1539, 1541,1542, 1543 | Jan 29
- Reception test for 1539 OK
- Cap gluing
Jan 30
- Reception test for 1541, 1542, 1543 OK
- Cap gluing
- FT:
-- 1539: C/B/B. First -20 is C due to INCOMPLETE TEST: DTB stuck
==> Must be retested at -20C and then files merging
-- 1541: C/C/C. Electrical Test is C due to Trimbit test failure in ROC13. Threshold is reasonable (see attachment)
==> Manually regraded to B
-- 1542: C/C/C. Electrical Test is C due to RelGain of 0.200 instead of <0.1 (too wide Gain distribution).
-- 1543: B/B/B (-20/-20/+10). Electrical Test is B due to mean noise >200e. |

Then cap gluing
Jan 29
- Reception test for 1540 OK
- FT:
-- 1536: B/B/B (-20/-20/+10). Electrical Test is B due to mean noise >200e. IV: 3umA for -20 and +10, slope >300
-- 1537: C/B/B. First -20 is C due ROC10 >200 TrimBits failure, noise >200e. IV: A
-- Trimbit test fails but Trimbit distribution is OK and Threshold reasonable (attachment)
==> Manually regraded to B
-- 1538: B/B/B (-20/-20/+10). Electrical Test is B due to mean noise >200e. IV: <0.2umA for +10, slope ~1
-- 1540: B/B/B (-20/-20/+10). Electrical Test is B due to mean noise >200e. IV: <0.8umA for +10, slope ~2.7 |

Andrey Starodumov | Full test | 4 modules FT | FullQualification of four modules M1526, M1529, M1521 and M1534 has been done. Full time of the test is about 5.5hrs.
Test included: FT@-20C, IV@-20, 3Cycles from -20C up to +10C, FT@10C and IV@10C.
Only M1521 passed the test (Grade B). Several issues observed in other modules:
1) 2-6 ROCs with TrimBit test failure for many pixels
2) Trimming id bad for some ROCs
3) test at +10C often better than at -20C
4) some ROCs hav issues with Thr and Gain distributions (out of specifications)
To be understood before the mass production! |

We have run with Urs TrimBit test for M1526 at room T (without turning ON coldbox)
and results are confirmed yesterday observations of TrimBit test failure of several ROCs.
Urs will take a look and try to understand the issue.
To illustrate the problem below two summary tables of M1526 at -20C and +10C are shown. |

Andrey Starodumov | HDI test | 4 HDIs tested | After staying in 90%+ RH 2 HDIs became flat. The first one was easy to mount on an HDI holder.
But after 1-2hrs the second HDI became bent again, but still remained flexible, so was also easy to mount.
I put 2 more HDIs in the same conditions and after 2 hrs was able to mount and test them.
4041, 4043, 3033, 3041 tested. All OK. |

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. |

Andrey Starodumov | HDI test | 3 HDIs tested | 5008 failed, but most likely die to the pin head mis-alignment. Test to be repeated.
5007 and 5008: passed tests but during HV measurements (-800V) with a multymeter I heard high frequency noise and instead of -800V measure either -100V or -500V but the voltage jumped significantly. This effect is to be understood.
For the moment these HDIs will not be used in production. |

Matej Roguljic | Software | Investigating the bug with the Keithley client | We took module 1529 and tried recreating the issue observed in the beginning of October. To do this in a reasonable amount of time, a "shorttest" procedure was defined which consists only of pretest and pixelalive. Three runs were taken
Run number 1: Shorttest@10,IV@10
Run number 2: Shorttest@10, IV@10,Cycle(n=1, between 10 and -10), Shorttest@10, IV@10
Run number 3: Shorttest@10, IV@10, Cycle(n=5, between 10 and -10), Shorttest@10, IV@10
In runs 1 and 2, IV was done from -5 to -155 in steps of 10
In run 3, IV was done from -5 to -405 in steps of 10
No issues were observed during the tests themselves.
Running MoReWeb shows the Temperature, Humidity and Sum of Currents plots while individual tests show only Pixel Alive map. IV plot is missing in the MoReWeb output, however, it is present in the ivCurve.log file. Tried investigating why IV is not shown, but couldn't get to the bottom of it.
Tomorrow we'll use M1529 and M1530 in a FullTest to check if the problem would appear. |
