Mark,

2 pm eastern on Friday would be a little early for me as I have a 
lecture that ends at 1:30, and then I go get something to eat, so I'd 
miss the first 15 minutes of so.

I'm a little nervous too about having the mini-torus upstream of the 
acceptance-defining collimator. I think the primary reason for going to 
the downstream collimator is to reduce the long tail at large Q^2 for a 
collimator close to the target - the geometry is not as well defined as 
the other option when the target has finite length.

I don't have anything to report except that I verified Neven's rate and 
Q^2 with his collimator, BUT, I'm find an asymmetric distribution in 
phi after the collimator, even though it's symmetric in phi just after 
the target. There's something wrong with the euclid file, but I haven't 
taken the time to track it down.

Jim
