TPC QA 2024

 
Goals and to do

Aim is to make QA more automatic at the FF and bad pad level.
The procedures to run ADC files last year seem good. Improvements are needed in the following area's

Update the AnaQA.C and associates cron job to execute task for both dead channels (FEEs, RDO and singles onesI include TPX too
and for hot channels to produce time sequence of changes.

The hots channel task was tweaked and looks fine.

Hot channels for cosmics April 2024

It is difficult to get enough statistics for cosmic data run. Two sets of run with plenty of ADC data was done thanks to Jeff.
104032-034 for FF field settting and
107059 for RFF setting 

The analysis result for channels to be masked permanently is

Sector,   row  pad
4         72   110
6         61    58
11         3    25
22        56    71
23        21    15

April 18 2024

Shift crew notice in run 109020 , cosmic, higher yield area. It looks like part of a FEE is misbehaving, could be
one event or few. Unlikely for all events. Sector 7, not in following run.






April 28
Something is not right in TPX Sector 3, RDO 4. Way too much data causing deadtime. One can see bad data in the online plots.
I powercycled it just now so let's see.

------------------------------------
Tonko: There seem to have been some electronics issues with the TPX03:4 RDO. This in turn caused a lot of data for that RDO which in turn caused the TPC to dominate the deadtime.
After powercycling the TPC deadtime is fine: 17% at 3.5 kHz.

I need to take a better look to figure out why the checking software didn't cause an auto-recovery. TBD.

------------------------------------
Tonko: The first errors started in run 25119018.
Run 25119017 was still fine.
And now run 25119024 is fine again.
