Weekly Meetings
- Meetings will be held on Thursdays 11:30-12:30 in F228.
- Next meeting March 10th.
- Join by Bluejeans by phone and computer +1.888.240.2560 (US Toll Free) Enter Meeting ID: 653182486
Preparation plans
- Magnets.
- Determination of B versus I curve. Develop new code for setting SHMS. Revise HMS field setting codes.
- Cycling procedure especially for HB. Look what is done for the HMS.
- Double check that the magnet field between magnets are superpositions.
- Survey of the positioning of magnets.
- Check if it is possible to do carbon elastics at 2 pass. Dipangkar will look into this. (Results for 1 pass- 2.2 GeV, and 2 pass -4.4 GeV)
- Survey of collimators, detectors and beamline components.
- Survey of HMS/SHMS pointing at different angles. Look into what was done in the past for HMS commissioning. Determine a list of angles for survey.
- Need to come up with the sieve pattern as a function of quad settings.
- Need to look at use of ideal dipole versus TOSCA field map for HB in COSY.
- Check with Howard about checking the quad field centering.
- Integration of detector checkout and optics.
