Comments: Start with access to put material in front of BB for rate check. At 1:45, remove shielding. 1:45-4:30 Rate scans. target dependence and raster-size dependence for 3He cell. 4:30-6:00 Beam position studies - trying to minimize drift chamber currents. High statistics runs, 3He with 3x3 and 1.5x1.5 raster. Start long H2 run. Get about 30 min and have problem with beam Target polarization measurement Emptry target test - DC current vs. large and small raster. (no run taken, just snapshots of current and trigger rates).
