STANDARD SETUP

SEQUENCE NAME

 DESCRIPTION
polbeam install This installs all devices. This is done at the beginning of the expt.
Qmode This sets the sample and guide field currents for P \(\parallel\) Q.
Vmode This sets the sample and guide field currents for P \(\perp\) Q.
pb SC7T MODE This sets the sample and guide field currents for the 7T SCM.

polbeam uninstall

 This uninstalls all devices. This must be done at the end of the experiment.

NOTE: If the server re-starts, uninstall all devices first and then run the sequence file to reinstall all devices.
