Abstract
A compact proton-beam therapy linac utilizing a linear, cascaded organization including a proton source, a radio-frequency-quadrupole (RFQ) linac coupled to the output of the source, a stepped-frequency (around 500- to around 100-MHz), low-peak-beam-current (around 100- to around 300-.mu. A) drift-tube linac (DTL) coupled to receive the output of the RFQ, and a plural-stage, low-peak-beam-current stage-switchable, side-coupled linac (SCL) coupled to the output of the DTL for producing the ultimate output proton-therapy beam.
