The beam was delivered at the begining of the shift. Due to pure running conditions with the BLAST field off the injection current was capped at 20 mA. The injection current was gradualy raised over the course of this shift to 40 mA. A higher injection current was attempted, but due to incessant tripping was dropped back down to 30 mA. Currently running at 30 mA injection current. The wire chamber scalers and coicidence trigger show very high rate. However, the signal-to-noise level in the WC is rather good at 4:1 in the worst case.
Runs 15772-15775 15777 15779 were taken and crunching (I assume with the regular BLAST field configuration as a default)
