8:00 to 830 finished elastic ep run for exp. 94-012
8:30 to 10:20 did Moller
10:20 started laser change in the injector to get more current (about 100 micro amps) for exp. 94-004.
During the time Moller was beging done changed angle and momentum in both spectrometers for exp 94-004 first point.
Hadron angle = 58.733 and electron angle = 15.995.
Hadron momentum = 0.890 GeV/s and Electron momentum = 2.760 GeV/c.
Ready to start the experiment when we get the beam.
13:45 started doing hHARP scan
14:45 did several harp scans (harp run 246 to 251). best MCC can do is horizomntal beam width at BPM 3B is 0.55 mm. The experiment 94-004 wants about 0.2 mm.
MCC calling optics expert.
14:55 now getting ready to do BCM calibration
15:00 BCM calibration canceled.
16:00 still doing harp scan. Horizontal beam width now 0.11 mm (ok) but vertical is about 0.4 and so MCC is still working to improve it.
