- CSF E97-006Progress, downtime (Marko Zeier)
- Showed chart for run downtime to date
- Problem with target lifter: 4h
- HMS: magnet trips
- ACC: 5h Hall A energy change
- Report on Experiment E94-110(Thia Keppel)
- Showed kinematic data from exp., what has been measured and what still needs to be measured
- They need (3.3) key energy to complete exp.
- Maybe 4/6 days left to run
- Discussed what they would like to get in 2 remaining energies
- Working on shift schedule to finish exp.
- Report on E91-016 (Joerg Reinhold)
- Discussed concerns of the minimum angles of the spectrometers
- Current minimum spectrometer angles are : HMS=12.5 degree, SOS=18.75 degree
- At small angles part of the SOS quadrupole support structure hits the girder
- It should be possible to move the girder towards the HMS side
- Another concern is the minimum opening angle between the two spectrometers
- HNSS update (Liguang Tang)
- Target was surveyed, it is now aligned
- Waiting for hodoscope to come in from Houston
- By the end of Sept., everything will be ready
- Waiting for French decission on what type of electronics they want to use
- Polishing of the NA scintillators have be done
- Magnet delivery schedule has been delayed 1 month
- G0 Collaboration Meeting will take place in TRIUMF on Sept. 24/25
- To get ready for Ingo's exp., what needs to happen
- Last fan went out, now being repaired
- Will need to repair the loops in 13 days
- Improve QA on the fan installation procedure
- Beam will be turned off on Sept. 1, and will start running Sept. 8
- Accelerator would like to survey on Aug. 31
- Bill Vulcan will reroute the wires in target chamber to avoid pinching
- Will need to replace the hydrogen
