** Anytime MCC turns OFF or ON Hall-C, HPS SVT bias HV must be OFF, SVT retracted to 3 mm position. After the transition is complete, and beam to Hall-B is established, perform 2H02 harp scan at 100 nA and compare with previous scans. IF consistent (within few 10s micron), precede with production running.
