11:05 Bias and leakage currents ok - attachment 1
FEE temperatures ok
System wide checks ok
Currently on file R9_74
Temperature 25.3C, Humidity 42.9%, D.P +12.1C
13:27 Bias and leakage currents ok - attachment 2
FEE Temperatures ok
System wide checks ok
Analysis of the pulser run R9_52 -> R9_74 has shown no major losses in terms of apparent broken bond wires.
The large gap in FEE64 29 can be explained by an ASIC dropping out: See https://elog.ph.ed.ac.uk/AIDA/730
Another odd trend appears in the channels relating to DSSD 8 on the x side. - attachment 5
The pattern shows one strip on one strip off for the first 32 strips.
nnaida18 is also the FEE which is running at a much higher rate during this run. - attachment 3
I'm not sure that I believe that these channels are actually relate to broken bond wires.
Here are the hit patterns for the 8 DSSD - attachment 4
Attached is also the x and y histograms for DSSD 8 which shows a weird pattern - attachment 5 |
