Smooth production data taking in Hall A since Chandan's last RC update. We ran on 3He except for brief interruptions to perform NMR measurements of the target polarization. At the request of the spokespeople we increased the beam current from 5 muA (https://logbooks.jlab.org/entry/4225300) to 7 muA at the beginning of the swing shift yesterday. The coin rate almost doubled compared to the 5 muA running reaching 6.6 KHz while the dead time increased to ~25%: https://logbooks.jlab.org/entry/4225300. We started having DAQ crashes so Alex advised that we reduce the beam current. We settled on 6 muA. The plan going forward is to continue production data taking on He until Monday morning when we will go in a Controlled access to change polarity for SBS and BB magnets. 

We will meet today at 3:30 to discuss the status of the run:
