Vertical polarization work is scheduled to start at 0800 presently. I
think that time only requires EGG okay to be set in stone. After
discussions with Reza/Arne, the current schedule is

   0800    Vert polarization setup (Joe/EGG, 2-3h)
           RF recovery (SL)
           0L02-3 checkout, other injector warm RF checkout
   1030ish Return beam to halls
           Hall C Moller measurement
   1300ish Reinstall Compton chicane setup
           Evaluate Compton backgrounds with current steering/setup
           Full-machine RF tuning (Reza) to improve Compton backgrounds
             if necessary

This should maximize time to the halls while achieving the Hall C
objectives of vertical polarization setup and Compton chicane back
in. If the Compton backgrounds are still excessive (possible but
unlikely given the halo rates), then we'll have to back out again
and consult with a larger group to develop an intervention plan.

                                                 -Todd
