We are continuing to take production data on the polarized Helium 3 target. Things have been generally smooth since beam was brought back yesterday (08/14) towards the end of DAY shift.

During DAY shift and into SWING shift, work was done on optimizing the QWP for both transverse LEFT and transverse RIGHT:
Transverse RIGHT ---- https://logbooks.jlab.org/entry/3827710
Transverse LEFT ---- https://logbooks.jlab.org/entry/3827373
Bill also updated the fit program (Polarization.vi) to ensure what the program does when it gets an error / fail fit ----  https://logbooks.jlab.org/entry/3827536

NMR measurements taken recently after the QWP optimization
Transverse @ 90 degrees (07:09):    42.0%----https://logbooks.jlab.org/entry/3827890
Transverse @ 90 degrees (02:00):    42.6 % ---- https://logbooks.jlab.org/entry/3827783

The plan remains to move to 1st pass on August 24th and move back to 5th pass on August 27th.

We will meet today at 4:15pm via Bluejeans 861439920 --- https://hallcweb.jlab.org/wiki/index.php/RC_Update_and_Run_Plan_for_Aug_15,_2020
