  1. Emulsion software and analysis Emulsion hardware 2003 Research History of Tsutomu FUKUDA • Analysis of DONUT experiment • Location of unlocated event 04 • dE/dX measurement in OPERA-film • Test experiment at KEK • Grain Density - dE/dX - beta • Sensitivity check by Temperature on Developing and Fading effect Pouring Nuclear- Emulsion for heavy ion exposure exp. 05 Master course • Tono-Refresh facility • Facility construction • Mass production shift leader • Refreshing control • Sensitivity check • fog density check OPERA ECC: VTX confirmation rehearsal by using PEANUT Brick 06 OPERA CS: Compton alignment test exp. by radioactive ray from KCl 07 PEANUT ECC: Systematic and Non bias ECC Analysis by SUTS data Doctor course OPERA ECC: VTX confirm in PLCh and Volume SCAN data Quality chk • GS-CS Refresh facility • Mass production shift leader • Refreshing control 08 OPERA CS: Direct VTX hunting and Organizer of CS Analysis at Nagoya 09

  2. CS status T. Fukuda on behalf of Nagoya CS Analysis task force team 20/Jan ‘09 OPERA–JAPAN (Mizunami) meeting

  3. Arrived & Sheeting Standard analysis stream of CS analysis TT check Brick o.k? No(clearly) Yes/?? Black CS? Yes No 1st CS analysis 1st CS analysis Not found TT check Brick o.k? ?? Found Found 2nd CS analysis Yes not yet Not found Found Not found Re- SCAN not yet Brick request Waiting / Not yet Re- SCAN Brick request Brick request Another analysis Not yet

  4. TT check. Brick o.k ?  No clearly Waiting for 2nd CS(26 -1 22 30)

  5. 580ev Status of CS analysis(up to 22/Dec arrived) TT check Brick o.k? No(clearly) Yes/?? Black CS? Yes No 1st CS analysis 1st CS analysis Not found TT check Brick o.k? ?? Found Found 2nd CS analysis Yes not yet Not found Found Not found not yet 36 109 6 6 290+8 45 80

  6. CS status (CC/NC)

  7. Recent CS status (19/Dec-10/Jan) About tracking efficiency 33 CC event Try center of Brick ? edge yes Muon found : 4 Muon not found : 5 24 9 Muon found? no yes 4/4 :20 3/4 : 2 4/4 efficiency = 83%  BaseTrk efficiency = 91% 2 22 Plate set at Scan and Scanning parameter tuning is improved (12/12 ’08). (Morishima-san’s talk) Tracking efficiency is better than before state. (BaseTrk eff: 82%  91% )

  8. CS analysis procedure • Scanning and Online data handling- Preparing 4/4 and ¾ track data set.K.Morishima • Track Selection for manual check- Compton AlignmentS. Miyamoto- Muon huntingY. Sakatani- Track rankingT. Fukuda • Manual check J. Yoshida- Navigation T. Yoshioka • Event validation  Decision of location method (SBL/DVh)
