 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
