0:00 Waiting for beam.
5:30 Got beam, starting carbon pointing runs, beam quality is low.
6:00 Moved sieve slit in on the right arm, starting run on carbon target.
We were not able to see sieve slit holes in the data. Took data for 30 minutes,
then moved target to LH2.
7:00 With 50uA on LH2 target rate of T5 trigger was 12.5Hz (10 of them
are supposed to be pulser). This looked low for elastic kinematics, decided to
move sieve slit out to see if the rate would increase. In the process of moving the
sieve slit on the right arm it was moved in the wrong direction and got stuck
apparently in its uppermost position. Tech on call has been called, hall is going
to controlled access.
8:00 Still waiting for the tech to come.
1049,1050,1051 cosmics to check detectors

1052..5:29/5:39...22K...carbon pointing, beam in the first ~2min
1053..5:45/5:57..61K....another pointing run, some beam trips
1054..6:02/6:32..153K....sieve in right arm, carbon target
1055 junk with LH2 target in (collimator is moving from sieve to uppermost position)
