Yesterday, a lot of time was devoted to working on issues in the 
accelerator, and on swing shift work was done on the beam tune to Hall 
C. Alternate optics solutions did not result in a good tune - one 
hypothesis is that some of the quads in the Hall C line might be at the 
wrong polarity (several quads had work of one kind or another done over 
the summer SAD). Quad polarities will be inspected in the hall and in 
the BSY today while the machine is down for RF recovery.

Hall C is presently in Controlled Access until about 1 pm . Please check 
in with the Shift Leader before entering the hall. Today's SWING shift 
3rd worker does not need to report, while the Wednesday OWL shift 3rd is 
on call.

We will have our usual Hall C RC meeting today at 4:15 pm:
