* Ask MCC to ramp the tagger magnet up to prepare for beam tuning.
* When MCC will inform you that they are ready to send beam, turn most sensitive detectors off including trackers (SVT, MVT, FTT, DC), Central Detectors (CTOF, CND) and RICH: refer to the manuals or call the experts for any questions.

* Before asking for beam, turn sensitive detectors off including trackers (SVT, MVT, FTT, DC), Central Detectors (CTOF, CND) and RICH: refer to the manuals or call the experts for any questions.
 
* 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.

* 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.
