STAR QA Board

["Tsang, Chun Yuen" <ctsang@bnl.gov>]

Dear Ashik,

 

As per our last QA meeting, we will not reject runs when number of events exceed a certain threshold no matter what the run log says.

 

Here’s the previous bad run sorted by number of entries,

 

Bad run	Entries	Reason
21257041	179879	BAD RUN: the run lasted 89 seconds < min threshold of 120 seconds.
21256007	875166	The run log for run 21256007 is empty
21257005	1523641	RDO failure, RTS02 was frozen.
21257010	1556013	iTPC S4RDO 4 failed, beam dumped without warning.
21258004	1958626	Unexpected beam abort, trip in TPC, ETOF.
21252021	2253290	ETOF busy, BTOF dead half-strip.
21211028	2580479	Run ends with CeC having problems
21226036	2972495	Beam lost mid-run
21226032	3000001	The run log for run 21226032 is empty
21256006	4078759	White path in digi density plot on strip 24-3-1, TPC sector 14 charge per pad plot looks abnormal.
21252004	4358544	BTOW problem, BBC E rate too high.
21252011	4621691	outer TPC 11-5 anode trip.
21240028	4988309	BTOW failure.
21258002	5382603	Drift velocity plot looks weird. Beam lost unexpectedly.
21252024	5700612	TPX 100% dead.
21252002	5920962	BTOW crates 0x15 0x14 show no entries.
21252006	6526676	ETOF EVB errors.
21257044	6673549	HV tripped in region 2 and 6.
21240018	7921464	ETOF EVB errors
21256015	8022496	The run log for run 21256015 is empty

 

 

I set the bad run threshold as 3,000,000. I choose this number because it’s a nice even number. The final bad run list then becomes,

 

Bad run	Entries	Reason
21257041	179879	BAD RUN: the run lasted 89 seconds < min threshold of 120 seconds.
21256007	875166	The run log for run 21256007 is empty
21257005	1523641	RDO failure, RTS02 was frozen.
21257010	1556013	iTPC S4RDO 4 failed, beam dumped without warning.
21258004	1958626	Unexpected beam abort, trip in TPC, ETOF.
21252021	2253290	ETOF busy, BTOF dead half-strip.
21211028	2580479	Run ends with CeC having problems
21226036	2972495	Beam lost mid-run

 

Here’s total event statistics,

 

Tot events	447,553,566
Rejected events	13,899,589
Rejected fraction =	3.10568166	%

 

I hope this helps.

 

Best wishes,

Tommy

Dear Sharang,

 

Here's my bad run list for FXT 7.2 GeV by reading online shift log with AI (specifically Microsoft Phi-4 Q4kM) assist,

 

Bad run	Reason
21211028	Run ends with CeC having problems
21226032	The run log for run 21226032 is empty
21226036	Beam lost mid-run
21240018	ETOF EVB errors
21240028	BTOW failure.
21252002	BTOW crates 0x15 0x14 show no entries.
21252004	BTOW problem, BBC E rate too high.
21252006	ETOF EVB errors.
21252011	outer TPC 11-5 anode trip.
21252021	ETOF busy, BTOF dead half-strip.
21252024	TPX 100% dead.
21256006	White path in digi density plot on strip 24-3-1, TPC sector 14 charge per pad plot looks abnormal.
21256007	The run log for run 21256007 is empty
21256015	The run log for run 21256015 is empty
21257005	RDO failure, RTS02 was frozen.
21257010	iTPC S4RDO 4 failed, beam dumped without warning.
21257041	BAD RUN: the run lasted 89 seconds < min threshold of 120 seconds.
21257044	HV tripped in region 2 and 6.
21258002	Drift velocity plot looks weird. Beam lost unexpectedly.
21258004	Unexpected beam abort, trip in TPC, ETOF.

 

 

The event statistics are:

 

Total number of runs = 87

Total Statistics = 447553566 = 447.55M

Rejected Runs = 20 (23.0 %)

Rejected events = 81095255 = 81.10M (18.1%)

 

I don’t know if you need ETOF. If you don’t, please remove any runs from the bad run list who is only there solely because of ETOF errors.

 

Best wishes,

Tommy

Dear Ashik and Tommy,

 

Please find attached the txt file with the list of total 87 run numbers for 7.2 GeV (FXT).

Please let me know if any other information is required from my end.

 

Thanks and regards,

Sharang
