RF System for the Indiana University Cyclotron Facility Cooler Project

The IUCF will take 200 MeV Particle beams from the cyclotron and lower their emittance via electron cooling. A further use for the Cooler is to increase the energy of the particles; it is proposed to accelerate protons to 500 MeV. The RF system for the Cooler must provide the voltage for acceleration, and also maintain the bunch structure to enable 'time of flight' experiments. The main RF system contains a cavity salvaged from the PPA which has been revised to operate from 6 to 20 MHz. as a bias tuned structure and also from 1.7 to 5 MHz. A UHF cavity tunable from 440 to 460 HMZ. provides 40 Kv. for tight bunching.
