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.

HMS Detector survey information,Magnet location surveys
File with B/I data and plots for dipole and quads.
Document about dipole field measurements.
Dipole Transfer Function which compares Tosca and measurements at probe and center.
Q1 Transfer Function plots and data
Q2 Transfer Function plots and data
Q3 Transfer Function plots and data
Note by Dave Mack on dipole current regulation.
Plot of Q2 predicted waist versus momentum for effects of zero offset.
Plots of quads effective field length.
Plots of quad fringe field.
Plot X_fp versus momentum.
