# <b> Run ends 6:45 am on Monday. Following has to be done:
 +
#* End the run, turn OFF HVs for all detectors, Start Ramping torus down to zero
 +
#* Retract the target using 2H01 expert GUI, just put -10 in the left "MoveAbs" and hit the return. Motor will go towards 0, and will hit "Lo Limit" limit switch
 +
#* Ask MCC to change beam current to 50nA with small steps, this is to calibrate SLM (data goes to MYA, but you can record beam current and the SLM reading if you want)
 +
#* When finished, got to 50nA, ask MCC to terminate the beam and take the Hall to restricted access.
 +
#* When torus reaches to 0 turn the PS OFF.</b>
