ABSTRACT:
A method and apparatus for controlling the delivered dose across a target area from an electron beam produced by a high energy, high power pulsed rf linear accelerator. Pulse width modulation as a function of scan position is applied to the rf drive pulses of the accelerator operated in a long pulse mode and fast feedback control is used to maintain uniform rf field intensity on an intra-pulse basis. In an alternative embodiment, rf drive pulses are inhibited as a function of scan position.
