* Prepare to re-establish beam following the "Establish-physics quality beam" procedure at [https://wiki.jlab.org/clas12-run/images/e/e3/Estab_beam.pdf]. Consult with the beamline expert in case of issues. | * Prepare to re-establish beam following the "Establish-physics quality beam" procedure at [https://wiki.jlab.org/clas12-run/images/e/e3/Estab_beam.pdf].

* Once beam is tuned to the FC, switched all detectors on. Call the SVT expert to switch the SVT on. Restore DC HV setting to be (8,9,9) for Region 1, 2 and 3, respectively. Make sure that the voltage for all channels comes up at the set values and no channels are off. | * Once beam is tuned to the FC, switched all detectors on. Call the SVT expert to switch the SVT on.
