6. Tracks while beam exposure. BL007 90 tracks. Position distribution OPERA film Y [cm] X [cm]

7. Tracks while beam exposure. BL007 90 tracks. Slope distribution NuMI beam tan(thetaX) ～ 0.054 tan(thetaY) ～ 0.000 tan(thetaX) tan(thetaY)

8. BL039 Transportation Jul. 2005 Brick Assembling23 minute Beam exposure Oct. 21-Nov. 3, 2005 Development Nov. 3, 2005 PL01 PL02 PL03 beam Transportation Pb

9. Tracks while beam exposure. BL039 73 tracks. Position distribution OPERA film Y [cm] X [cm] dX= 25 micron dY= 7 micron Brick assembling accuracy （ BAM ） Marvelous !

10. Tracks while beam exposure. BL039 73 tracks. Slope distribution NuMI beam tan(thetaX) ～ -0.054 tan(thetaY) ～ 0.000 tan(thetaX) tan(thetaY)

11. BL040 Transportation Jul. 2005 Brick Assembling25 minute Beam exposure Oct. 21-Nov. 3, 2005 Development Nov. 3, 2005 PL01 PL02 PL03 beam Transportation Pb

12. Tracks while beam exposure. BL040 131 tracks. Position distribution OPERA film Y [cm] X [cm] dX= -14 micron dY= 15 micron Brick assembling accuracy （ BAM ） Marvelous !

15. Summary S-UTS version-0 works well for large area scanning. ～ 100 tracks / brick found as beam-related tracks without SFT information. Scanning of other bricks are on progress. Track follow procedure is now starting. PEANUT shift members work well ! Brick assembling accuracy is good.

16. 131 tracks/80cm 2

18. Outlook Also BL039 PL01+PL02 has done Track scanback for these tracks –BL007,BL039,BL040 –Narita work on this subject SFT to Brick matching –Nonoyama MINOS to SFT matching –Gina
