Analysis of SynchTriggerNoise data from Alan Phillips:
The Following reports for Barrel3 and Barrel6 have been corrected so they now consider the right number of triggers:
Re-analysis (online) of SynchTriggerNoise data; as reported by Bilge Demirkoz
For Barrel4, the interesting runs to look at are:
- 9482.0: STN before TxDelay adjustment 01/08/2005 20:55
- 9497.0: STN after TxDelay adjustment: ie. triggers are more synchronous. 02/08/2005 15:58
The only OPE feature is on 20220170200257 from run 9482.0 at 0.95fC, there is one OPE blip. Nothing to worry about. But is there anything else special about this module?
Strangely enough, the noise for 9497.0 is lower than that of 9482.0. The online analysis did not work during the datataking and so the DCS information has not been recorded with these modules. But the stave temperatures were the same for both runs suggesting that the noise difference between these runs is due to other factors: 1) light on the modules -- unlikely, should be the same for both cases. 2) time since turn on of modules. It is well known that the noise goes down and eventually settles with time after turning on the HV. 9497.0 was at a later time from HV turn on.
For Barrel5, the data was analyzed offline. Run: 1553.7 from CERN dataset.
