Refresh facility ( T.Nakamura )

Refresh chamber installation will begin next week. First delivery will be in August as scheduled.

Exposure setup ( A.Ariga )

Mechanical work was finished. SFT calibration is in progress. photo or report on 030608

Automated development system ( N.Naganawa and S.Ishikawa )

Ready to develop real emulsion sheets. photo

X-ray mark ( M.Uno )

The simplest mark ( only 1 line ) looks promising. Cupper slit is being prepared.

S-UTS ( T.Nakano )

Debugging is in progress. photo

Stack to stack ( brick to brick ) connection in CHORUS ( O.Sato )

Recent progress in CHORUS ananlysis enables us to connect a track in a stack ( brick in OPERA ) to other stacks. Calibration of about 100micron over 1.4m x 1.4m was proved to be possible.

Components of event location are almost ready. No preparation has been done for sheet exchanger in Japan but Bern prototype is rather promising,

Test in F-lab

After SFT calibration, SFT to CS connection and scan back in a brick should be tested using mini-OPERA setup. All steps as described below should be tested before the setup is brought to KEK.

• Brick packing in F-lab ( to be moved to TONO when the facility is ready )
• Exposure to cosmic rays with SFT DAQ
• Development by automated development system
• Scanning with UTS ( S-UTS will be used when ready )

Test in KEK PS

Proposal should be submitted ASAP. When it is submitted, beam line study using a fiber block should be arranged.

Possible upgrade of mini-OPERA as an replacement of OPERETTA

OPERETTA status was presented briefly by Imad. A possibility to upgrade mini-OPERA setup ( i.e. 5 walls, each having 5x5 bricks, and 5-6 TT planes ) was suggested as a replacement of OPERETTA for neutrino beam exposure.

Discussion about TT.(on 16th)

There are already useful TT planes and DAQ system in Lyon.
Who does treat it? and How to install it?
