====== Changing Between Beams Within A Cocktail ======
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.

===== Steps: =====

  - 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
  - Increase chopper duty cycle to 100%
  - 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
  - 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
