Features of Fast Output Energy Regulation in a Linear Accelerator for Proton Therapy

In the paper, the results of studies of processes during fast output energy regulation of a linear accelerator for proton-beam therapy during one RF pulse have been summarized. Both the features of the formation of the required RF power pulse and the propagation of the RF pulse in an inertialess dispersed structure on a traveling wave have been considered. Particular attention has been paid to the dynamics of particles in a nonstationary electromagnetic RF field. The use of the considered regulation method will allow a multiple increase in the scanning speed along the depth of the irradiated object.
