| 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.
