CSC DCS DQA Status ØInfo being written to COOL includes n Low voltage state w 0 for off, 1 for on and -1 for unknown n High voltage state w 0 for off, 1 for on and -1 for unknown n n High voltage set points 0 and 1 CO 2 concentration status w 0/1 for outside/inside limits 2

CSC Online DQA Status ØDQ calculator n n An algorithm for the DQ calculator exists CSC group needs to converge on definitions of green, yellow, red states 3

CSC Online DQA Status Ø CSC GNAM monitoring n n Successfully exercised and used during August 09 muon combined running A newer CSCGNAM release has small modifications A second CSCGNAM release (1 -2 weeks) will complete implementation of a set of histograms common to online and offline Need to move root file storage from pc-csc* to pctdq* for Co. Ca archiving to CASTOR Ø CSC OHP n Successfully exercised (but slow) during August 09 muon combined running 4

CSC Online DQA Status Ø CSC DQMF configuration n DQMF segment was not tested during August 09 muon combined running w Request to Michael Schernau to test this in standalone ASAP w However offline tests show it works n DQMF will write two DQ flags (A side and C side) to COOL w Still based on channels found in (which? ? ) hit maps w Will test during upcoming muon combined run w Next version will include some CSC specific DQ algorithms – ready in 1 -2 weeks 5

CSC Online DQ Flags Ø Now n n n ROD errors ROD cluster, strip and ANA cluster strip hit maps …which algorithms are used? Ø Soon n Landau distribution fits to cluster charge by layer … …which hists and which algorithms? Ø Additionally we have made provision to write side, chamber, layer DQ flags to the CSC COOL db n Needs to be automated 6

CSC Offline DQA Status ØCSC Tier 0 monitoring n n Run 125032 (from August 09 combined run) processed by hand Significant effort by V. Kaushik and W. C. Park to (again) validate Tier 0 monitoring AND CSC/Muon reconstruction To my knowledge, all bugfixes, etc. have been tested and submitted Up to K. Black et al. if CSC monitoring and reconstruction will be turned on by default 9

CSC Offline DQA Status ØCSC Tier 0 monitoring continued n Nevertheless, Tier 0 (and online) monitoring gave the CSC group a fast and informative look at data from the August running ØCSC HAN configuration n Complete but not tested Sent to I. Nomidis for inclusion in the Muon System configuration Initial DQ checks in place but must write CSC specific algorithms for final checks 10

Offline CSC DQ Flags Ø Now using n n n RDO, PRD and cluster layer and channel hit maps Precision cluster sampling timing Algorithms used are Histogram_Not_Empty and Check. Histo_Mean Ø Soon will add checks for n n n MPV of precision cluster charge % bad precision cluster sampling time Cluster layer hit map occupancy Cluster strip hit map shape Segment efficiency Ø Additionally we have made provision to write these values for side, chamber, layer DQ flags to the CSC COOL db n Can DQ Calculator access these? 11

Run 125032 ØLayer and channel hit maps – side C 13

Run 125032 ØCluster peak strip charge (top) and total charge (bottom) for A and C sides 14

Side A (+1 to +16) MPV of fit shown Run 125032 to -16) Side C (-1 MPV of fit shown ØSample DQ flags from Landau fit A: Qsum distribution per layer C: Qsum distribution per layer 15

Conclusions Ø DCS n Must converge on green, yellow, red states Ø Online n n Initial DQ check and COOL storage in place Need to move to “final” DQ checks using CSC specific DQ algorithms Ø Offline n n Initial DQ check in place Need to move to “final” DQ checks using CSC specific DQ algorithms Storage of DQ info to CSC COOL db defined Outstanding question is if/how DQ calculator can access CSC COOL db 16
