Minutes of Regular Hall C Meeting

September 27, 1999 @ 3:00 p.m.

************************************************************************

• Engineering (Bill Vulcan)

• Power supply of HMS dipole was tripping at 1800 Amps, restricted running
• Problems with Quad, it appears to be coming from connection to the interlock
• Need to order more cables for Tang's exp.
• Need to order (30) fans for the power supplies
• Looking into getting patch panels on the main frame for G0 magnet

• CSF E97-006Progress, (Daniela Rohe)

• Reported on beam time that was taken on E97-006
• No beam due to lots of problems in the accelerator. Afterwards major HMS problmes: main reason-leak in the helium tube, bad interlock interface, one cable was not connected right
• Had lots of data acquisition problems
• At the beginning of beam time, the pumps which evacuate the HMS and SOS were not switched on
• Also found that the power supply for the rotation of the SOS was not switched on

• Report on Experiment E94-110(Rolf Ent)

• Data analysis is going good
• Run plan is being prepared
• Shift schedule is being prepared, need volunteers
• Experiment is scheduled to start running on Oct. 5-11

• HNSS General (Y. Sato)

• Modified the "Engine" library to delete HMS related part and add HNSS part
• New software library "Ktracking" for HNSS is now available
• Generation of dummy data in the CODA data format by the GEANT simulator
• Debugging and calibration of HNSS and SOS subroutines and/or parameters
• New subroutines for physics data analysis
• Simulation for the calibration procedure by p(e,e'K+) Lambda reaction
• CODA setup for SSD and hodoscopes is available at EEL building
• Whole setup is now under construction. New read out lists TS, scalers, and so on should be prepared
• Slow Control - now under consideration. We should list up what kinds of parameters are registered

• Gen (Dick Madey)

• Submitted 3 sets of cables, numbers, lengths and types needed
• Regular working group meeting took place last Thursday, will have another one this Thursday

• G0 (Allison Lung)

• Good progress on the construction
• Delivery schedule for the French electronics and detectors were discussed
• Magnet delivery schedule has not yet been determined
• Controls for magnet has not been worked on yet
• Background study needs to be determined

• Comments (Roger Carlini)

• Accelerator was late getting turned on, power supply trouble
• Interviews for the Hall C coordinator will take place on Wednesday
