Modules tested on May 5th
M1574: Grade B due to mean noise >200e in ROC10 and trimming failures for 89 pixels in ROC0, the same as the first time April 24 (there 104 pixels failed)
M1581: Grade B due to mean noise >200e in ROC8/13, no trimming failures in ROC8/13, as it was on April 27 (120+ pixel in ROC8/13 failed) -> Resalts improved!
M1660: Grade B due to mean noise >200e in few ROCs, no more trimming failure for 172 pixels in ROC7 as it was on April 7 in ROC7 -> Results improved!
M1668: Grade B due to mean noise >200e in few ROCs results are worse than were on April 14: one more ROC with mean noise > 200e
resume: for 2 modules results are improved for 2 others almost the same |
