Abstract
It is proposed to accelerate ions in a fixed-frequency cyclotron, either with the dee voltages 180° out-of-phase, or with the dee voltages in-phase. This is possible if the angular extent of the dee electrodes is made less than the customary 180°. Formulas have been derived for the energy gain per turn of ions with various charge-to-mass ratios as a function of the angle of the dees. The threshold dee voltage for acceleration to a given energy is somewhat larger than that for conventional two-dee cyclotrons. For appropriate dee angles it is shown that both protons and deuterons can be accelerated in the nonrelativistic energy region at substantially the same magnetic field and oscillator frequency. Suggested applications to acceleration of ions heavier than alpha particles are discussed.
