<!--* If beam profiles at the tagger are acceptable, move to beam tuning to the Faraday Cup. Again, refer to the instructions in the "Establish-physics quality beam" procedure at [https://wiki.jlab.org/clas12-run/images/e/e3/Estab_beam.pdf]. Compare harp scan with the one from 1/25 swing shift (https://logbooks.jlab.org/entry/3520947). --> | <!--* If beam profiles at the tagger are acceptable, move to beam tuning to the Faraday Cup.

<!--* Once beam to Faraday Cup is established, prepare to start data taking. Switch on all detectors; contact expert to switch on SVT. Start trigger studies following instructions from the DAQ expert. --> | <!--* Once beam to Faraday Cup is established, prepare to start data taking.
