View source for Beam Recovery Procedure

=== After beam study or other major down time ===
# Move target to '''Empty''' position, let MCC restore the beam. 
# Move target to '''BeO/Optics''', ask Raster OFF.
# Then let MCC tune the beam to our nominal beam position (BPM values are on the white board) with low current (<=2uA). On the monitor, verify the beam is hitting the center of the cross-hair marked on BeO target.
# Move target to '''Empty''' position, ask MCC to do a Harp Scan, the beam profile should be within 100-200 um (both X and Y sigmas).
# Move target back to '''BeO/Optics''' position, ask for 4x4 raster (6.5x6.5 MCC units) and 2 uA beam. Take a short run using LHRS DAQ w/ T3 only then do spot++ to check raster size.
# Move target to '''He3''' position, keep the 2x2 raster size (3.3x3.3 MCC units). Ask for 2uA beam and compare the T3 trigger rate with previous log (posted on the right side of the scaler monitor).
# Keep 2uA beam, change raster size from 2x2 to 6x6 (9.8x9.8 MCC units), verify that there is no significant change in the T3 rate. Do spot++ to check raster size and any hot spot.
# Once everything looks normal, change raster size back to 4x4 (6.5x6.5 MCC units). Ramp the beam to 10 uA and compare the trigger rates with previous log (also posted on the right side of the scaler monitor).
# Continue production.

=== After not very short beam down (>1hour) ===
# Move target to '''BeO/Optics''' position, ask for 4x4 raster (6.5x6.5 MCC units) and 2 uA beam.  On the monitor, verify the beam is hitting the center of the cross-hair marked on BeO target. Take a short run using LHRS DAQ w/ T3 only then do spot++ to check raster size.
# Move target to '''He3''' position, keep the 4x4 raster size. Ask for 2uA beam and compare the T3 trigger rate with previous log (posted on the right side of the scaler monitor).
# Ramp the beam to 10 uA and compare the trigger rates with previous log (also posted on the right side of the scaler monitor)..
# Continue production.
