A PROGRAMMABLE RADIO FREQUENCY WAVEFORM GENERATOR FOR A SYNCHROCYCLOTRON

摘要

The invention relates to a synchrocyclotron comprising a magnetic field generator, a resonant circuit comprising electrodes disposed between magnetic poles having a gap therebetween across the magnetic field, a variable reactive element in circuit with the electrodes to vary the resonant frequency of the resonant circuit, and a voltage input to the resonant circuit, the voltage input being an oscillating voltage. The synchrocyclotron is characterised by a feedback system that varies the voltage input over the time of acceleration of charged particles.
