Scanning coordination and shift organization in Bern (1)
3
• Location speed in Jun-Aug was not stable– Manpower for scanning
• 3-4 physicists are reduced from scanning shifts.
– 4 microscopes devoted to OPERA– July was vacation season in Switzerland– Main manpower was used for the test exposure at CERN in Aug
(~1month)
• Thanks to Çağın Güneş (Ankara) for her contribution from July• A new guy (non physicist) started to help data taking from 2weeks ago
• New strategy– Prediction scan base -> volume scan base (location quality does not change)– Reduce human needed work even increasing scanning time
– Reduce dead time of 4microscopes with plate changer (night, weekend) may increase location speed factor ??
– Now trying to establish new way..
Scanning coordination and shift organization in Bern (2)
CS prediction
Volume scan
Manual confirmation
• One of bottle neck: problems on lateral marks for the already delivered bricks (some lines too near to edge or too thin)– Problems were investigated by BH people.– Please monitor regularly at GS.
• Examples
Scanning coordination and shift organization in Bern (3)
• Remote monitor for night and weekend
Scanning coordination and shift organization in Bern (4)
4 microscopes can be remotely monitored
by a person.
Mark measurement can be helped manually
by remote.
An example automatic measurement failed (horizontal line near to edge and some scratches)

Possible gamma off vertex?(event10189040923)
• A track with IP 338m to 1ry.– p ~1GeV– possibility not excluded.
• Under checking– Some other tracks not confirmed in vertex plate.– Efficiency is bad..
1mm
Summary and prospect
• Location speed in Jun-Aug was not stable with manpower problem and lateral mark problem.
• Now trying to increase location speed by reducing dead time of microscopes.
