Running 90 % of SUTS machine time used for CS scanning 10 % of ECC volume scan using 1 SUTS (normally SUTS02 or 03) 4 SUTS (01/02/03/05) 9.8 CS/day → 68.6 CS/week 5 SUTS 12.6 CS/day → 88.2 CS/week SUTS Scanning Shift SUTS Running Speed

CS Data Taking （ first scanning ） ■ SUTS01 ■ SUTS02 ■ SUTS03 ■ SUTS05 Flat area : Re-scanning

Stream of scanning and processing : CS change plates Making MicroTracks Making BaseTracks Compton Alignment Online scanning monitor Optimize the parameter of scanning and the flow of the processing Check qualities of all events and Judge whether to do manual-check or re-scanning 3/4 connection 4/4 connection selection Online process : CS Morishima Manual check list Check monitor When the trouble occures, call to Morishima → automation Online processing monitor shifter CS

Improvement of scanning qualities Side view of the surface recognized by suts GOOD BAD Bad Ratio : ~ 10 % Now : ~ 2 % Training and carefully setting 1.Condition of scanning parameter is changed (set the lowest threshold to secure base track efficiency more than 93% (now, only CS, not yet ECC) ) 2 ． Plate setting Result in these effects will be presented by next talker T.Fukuda 100 micron Air enters under film, and it is floating

ECC data Tracking efficiency distribution of some bricks efficiency Solution ・ Slow speed scanning ・ Two or more recognition boards are used for one SUTS (one present) Background component is different from CS. Not fog but compton tracks are the main.

Summery 5 SUTS are running CS scanning speed ~ 88 CS/week Improving the qualities by changing the parameter setting and the plate setting. In near future, CS data quality check will be automated as soon as possible, and built in the shift task. I make efforts to the improvement of the data taking and processing of ECC for Vertex Confirmation and Decay Search Analysis.
