Abstract
Official abstract text for this publication.
A synchrocyclotron includes magnetic structures that define a resonant cavity, a source to provide particles to the resonant cavity, a voltage source to provide radio frequency (RF) voltage to the resonant cavity, a phase detector to detect a difference in phase between the RF voltage and a resonant frequency of the resonant cavity that changes over time, and a control circuit, responsive to the difference in phase, to control the voltage source so that a frequency of the RF voltage substantially matches the resonant frequency of the resonant cavity.
First claim
Opening claim text (preview).
What is claimed is: 1. A synchrocyclotron comprising: magnetic yokes that define a resonant cavity; a source to provide input voltage to the resonant cavity, the source comprising a voltage controlled oscillator (VCO); and feedback circuitry to control the source so that a frequency of the input voltage substantially matches a resonant frequency of the resonant cavity, the feedback circuitry comprising: a phase detector to detect a phase difference between the frequency of th…
