First tests of a CW RFQ injector for the IUCF cyclotrons

A 750 keV proton injector is being installed in place of a 600 kV Cockroft-Walton high voltage terminal at the Indiana University Cyclotron Facility. The injector features a microwave ion source, a 20 keV to 750 keV CW RFQ and a quadrupole triplet to focus the beam into the 15 MeV injector cyclotron. Two solenoids and one pulsed lens are used to match the 20 keV proton beam to the RFQ and to rapidly change the beam intensity. The injector has been tested offline; the results will be described in this paper.
