[Tpe] two-pass running

[Larry Weinstein]

Dear Folks,

We would like to run 2.2 or 1.1 GeV primary electrons (at 1 nA or less) 
through CLAS with a) the torus on at nominal field and b) the torus off 
for straight tracks.  This would impact other halls because it would 
take about 4 hours to tune the beam for us.

Hall C might not be able to take beam tomorrow during the day.  If so, 
do we want to do the lower energy primary beam run then?  If we do that, 
then we should measure the beam (empty target then do calorimeter runs) 
first.

Please comment.

-- 
				Sincerely,
				Larry
