Logentry Text:
We re-started the calibration from W69 (3rd crystal row) due to the Y position shift in HyCal movement.
Start time: May 29, 11:13:05
End time: May 29, 11:53:33
Some problem observed from this scan:
We can barely see the dynode sum peak, and comparing what we saw from lead glass scan, the dynode sum amplitude is very low. The dynode sum amplitude is about 70 - 80 mV.
We plan to do a quick test at the crystal module, only use total sum trigger to see the dynode sum amplitude.
