The IUCF Transfer Beaime

The transfer beamline between the injector stage and main stage cyclotrons has been designed, constructed and is under test. The beamline provides a good match between the calculated extracted phase space ellipses in the injector and the inflection requirements of the main stage over a wide range of particle types, emittances and energies. Energy dispersion of 0.07% FwHM for 16 MeV protons is available at a waist. Attempts were made to minimlize time dispersion; as a result the time spread through te transfer system is negligible for light ions. For 12C(14+) the time spread will cause an energy spread in the main stage at 200 N4eV of about 100 KeV, under normal operating conditions.
