All time estimates in the overview assume 50% Hall C + Accelerator efficiency,
including configuration change time and a beam current of 65 <math>\mu</math>A. \<center><math>2ex]<br/>
\subsection*{Last shift before Experiment begins:}<br/><br/>
#{All spectrometer magnets on to correct polarity and cycled to initial
values. Spectrometers also at initial angles.}<br/>
#{Check that no new obstructions have appeared since the spectrometer
angles were certified. For example, ladders, RadCon survey ropes, etc.}<br/>
#{Double-check HMS/SHMS Gas Cerenkov pressure is at correct value.}<br/>
#{Verify there are no obstructions between the detectors (ie, no WC covers,
no dangling cables, etc.) on both spectrometers.}<br/>
#{Verify there are no unusual obstructions between the scattering chamber
and the spectrometer front windows. Make sure any protective windows on the
scattering chamber have been removed.}<br/>
#{Lock up the hall.}<br/>
#{Clean up the counting house. Make sure all terminals, consoles, and printers are alive and well.}<br/>
#{Take a cosmic run and look for problems.}<br/>
