Andrey Starodumov | Full test | FT of M1606, M1630, M1655, M1566 | 
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 
M1655: B due to mean noise of several ROCs> 200e 
M1656: B due to mean noise of several ROCs> 200e |

Andrey Starodumov | Reception test | RT of M1567 failed | 
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

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. |

Andrey Starodumov | Full test | FT of M1593, M1658, M1659, M1660 | 
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, |

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. |

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. |

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.  |

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. |

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 |

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.  |

Andrey Starodumov | Full test | FT of M1654, M1665, M1666, M1667 | 
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! |

Andrey Starodumov | Reception test | RT of M1623, M1657, M1673, M1674 | 
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 |

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. |
