 Beams changes within a cocktail may be completed quickly by changing the main field of the cyclotron and a limited number of changes to other beamline devices. The intention is to change the least number of devices while producing the same beam quality delivered to SEE. Beams changes within a cocktail may be completed quickly by changing the main field of the cyclotron and a limited number of changes to other beamline devices.

-Steps:+===== Steps: ===== 
   - Run main probe in to 24"   - Run main probe in to 24"
     - This process could be done on FC2007, as long as the beam intensities for all beam species is within acceptable levels     - This process could be done on FC2007, as long as the beam intensities for all beam species is within acceptable levels
Line 8: Line 9:
   - Set the main field epsilon value to the new value   - Set the main field epsilon value to the new value
     - If the value is already logged/known, use that. Otherwise use the value from Analog Beams and add the offset for the pilot. e.g. Pilot is at -300 ppm, new beam expected at +5000 ppm, set field to +4700 ppm     - If the value is already logged/known, use that. Otherwise use the value from Analog Beams and add the offset for the pilot. e.g. Pilot is at -300 ppm, new beam expected at +5000 ppm, set field to +4700 ppm
 +  - Set the MHB F1 phase to the new value if known
 +    - If value is not known, maximize beam current on probe by adjusting MHB F1 phase.
 +  - Set the beam intensity to acceptable levels using chopper
 +  - Extract the probe and send beam to FC2007
 +  - Make additional adjustments to a minimal amount of devices. Observations have shown that the D0864 dipole will need to be adjusted, possibly the D0899 dipole
 +  - Send beam to end of SEE line FC2192
 +    - This may be done with small beam or uniform beam
 +  - Adjust HEBT dipoles (D2048 and D2060) to maximize current on FC2192
 +  - Set up uniform beam
