  1. Tomokazu Matsuo TOHO University. M2 Experience: CS Production in Gran Sasso CS Scan, Manual check ECC Vertex analysis Main works: Make plate changer #2. Scanback task force member.

  2. Direct ScanBack - Scanback without SUTS - TOHO Univ. Tomokazu Matsuo Nagoya Univ. N. Kitagawa, M. Kazuyama, Umut Kose, T. Naka. Aichi Kyoiku Univ.K.Kodama 2009-01-20

  3. Direct Scan Back location(DSB) Scanback without SUTS scanning PL 1,2 Start from Dec./'08 First method DSB method CS (SUTS & UTS) CS (SUTS & UTS) PL1&2 (SUTS & UTS) Scanback (PLCH with navigation) Scanback (PLCH without navigation) ECC volume scan (SUTS) ECC volume scan (SUTS) If DSB failed >> SUTS PL1,2 scan

  4. Merit * save time 1st method: 30min (PL1,2 SUTS scan) + SB DSB: <10min (find track on Pl.1) + SB System upgrade: Semi-automatic CS X-ray measurement soft * save machine resource SUTS: 30 min/ev. * skip process Cut the waiting time > analysis speed up Save human resource

  5. Result of DSB 8 vtx confirmed 23 connected 12 stopped 34 DSB 3 penetrate or edgeout Go to PL 1,2 SUTS Scan 11 not connected SUTS load 1/3

  6. Unconnected events Strategy: Scan PL.1,2 by SUTS Sendback to CS 2 1 inefficiency of drylens Recovered 2 11 total 1 bad parameter (already fixed) Wait scanning 7

  7. Track position and angle in Pl.1 that connected from CS to Pl.1 Tracks of 23 connected events

  8. The difference between Prediction calculated by tracks on CS and Tracks found on ECC

  9. Summary We have started a new procedure, DSB We can Save Resource (SUTS,UTS) Success ratio is 70% now. >> It will become better.

  10. ここまでしかないよ

  11. 2 Recovered 1 Edge out 1 Wait scanback

  12. 2 Recovered 1 drylens 1 bad parameter (already fixed)
