BLAST toroid on, out-bending field.

CCR delivered beam around 21:00. Good BQM's 130/40/35/25 and lifetimes around 25'

Started taking data with unpolarised H running 1 torr in the buffer volume.

Using l2trig and new_phys.settings. Trigger rate is around 400Hz for 50mA at level 1 accept and 30Hz for 50 mA at level 2 accept. WC's look good.

LADS L15_R7 tripped repeatedly and the HVGUI does not seem to be controlling that channel. In the end gave up and turned LADS off.

Perhaps this also caused the neutron scalers to be all zero too but I ignored it until Michael can look at it tomorrow.

Started crunching runs. Error about scaler target not defined error message which Chi reported a few days ago. Ignored this too.
