M1606: B due to mean noise of several ROCs> 200e
M1639: C* due to failure many pixels of ROC1 at +10C as before: to be run at +10C with CtrlReg=17

After exchange of TBM1 the results is the same:
WAS:
1567: Grade C, no data from ROCs 8-11, looks like a problem with one TBM1 core
NOW:
-during ThrComp-CalDel scan: WARNING: Detected DESER400 trailer error bits: "IDLE DATA"
- result: INFO: CalDel: 135 134 126 121 158 141 119 133 _ 124 _ 107 _ 126 _ 108 133 91 138 120
ROC8-ROC11 no hits! |

Tue Apr 7 15:25:21 2020, Andrey Starodumov, Reception test, RT of M1662 failed
|
Address decoding of M1662 failed in one double column of ROC4.
To be decided what to do with this module.
Currently in C* tray. |

|
M1593: B due to Rel.gain width and mean noise of a few ROCs
M1658: B due to threshold and mean noise of ROC15
M1659: B due to threshold and mean noise of a few ROCs
M1660: C due to 172 pixels failed Threshold (trimmed) on ROC7 only at second -20C, the first -20C and +10C trimming threshold is OK for this chip
M1660 to C* tray and retest with all other modules after production, |

Tue Apr 7 17:59:27 2020, Andrey Starodumov, HDI test, 6 HDIs tested

HDIs
2030, 2031, 1021, 1022, 1023, 1035
are tested. All OK. |

Tue Apr 7 18:02:07 2020, Andrey Starodumov, Reception test, RT of 1654
|
After Silvan removed a cap and re-bonded broken and bent wires M1654 again has been tested.
RT grade is A.
Protection cap to be glued and to be (F)tested. |
|
Wed Apr 8 13:40:45 2020, Andrey Starodumov, Reception test, RT of M1625 failed
|
Silvan substituted TBM on this module.
Now ROC0 does not have hits.
Grade C, goes to "Bad" tray. |
|
Wed Apr 8 13:43:15 2020, Andrey Starodumov, Reception test, RT of M1623 failed
|
M1623: all ROCs are programmable but no readout from ROC8-ROC11.
Visual inspection is OK.
To module doctor. |

Wed Apr 8 15:02:37 2020, Andrey Starodumov, Software, Change of CrtlReg for RT
|
So far in a blue box for RT tbm10d_procv3 parameters were used.
This is wrong, since CtrlReg=9 is better for -20C while for +10 or higher T
CtrlReg=17 is better.
From now on for RT tbm10d_procv4 will be used. |
|
Wed Apr 8 15:20:38 2020, Andrey Starodumov, Reception test, RT of M1665
|
With CtrlReg=9 RT grade was B due to 90 noisy pixels in ROC5.
Noisy in this case means that one pixel in a 2x2 cluster in a few column got 40 hits instead of 10.
With CtrlReg=17 this problem gone. RT grade is A. |

M1572: Grade B due to mean noise of ROC4 211 electrons
M1661: Grade B due to mean noise of a few ROCs > 200 electrons and in ROC12 44 pixels failed threshold cut
M1663: Grade B due to mean noise of a few ROCs > 200 electrons
M1664: Grade B due to mean noise of a few ROCs > 200 electrons and in ROC12 44 pixels failed threshold cut |

Currently in C* tray. |
With CtrlReg=17 the grade of module is B. Still in one double column "noisy" pixels: with hits from other 3 pixels of a cluster.
Stay in C* tray. To come back later. |

Thu Apr 9 14:49:07 2020, Andrey Starodumov, Reception test, RT of M1650 failed

Module has been tested on April 2nd.
Under Molex connector in ROC12 471 dead or noisy pixels.
Grade C. |

M1654: Grade A
M1665: Grade B due to noisy pixels in ROC5. To be checked by module doctor!
M1666: Grade B due to mean noise of several chips > 200 electrons. Again on ROC12 there is a cluster of 31 dead bumps!
M1667: Grade B due to mean noise of several chips > 200 electrons. Again on ROC12 there is a cluster of 41 dead bumps!
M1665 goes to Module doctor! |

ROC12-ROC15 no hits.
A candidate to TBM0 substitution, hence Grade C*.

M1623: Grade A, should be B due to 71 bump defects in ROC4
M1657: Grade B, due to 51 dead pixels in ROC12
M1673: Grade A, again 31 dead bumps in ROC12
M1674: Grade A, again 39 dead bumps in ROC12 |

Tue Apr 14 16:54:31 2020, Andrey Starodumov, Other, M1633 cable disconnected
|
We do not have any more module holders.
M1633 was in "Module doctor" tray.
I took module off the holder and put it in a gel-pak. |
