Usage of a small-sized betatron with extracted electron beam for radiotherapy of surface neoplasms

Investigation results of spatial and energy characteristics of electron beam of the PMB-6E portable betatron with azimuthal variation of the magnetic field and beam extraction by the resonance method are presented. The betatron is intended for treatment of surface new formations, and the energy of electron beam is regulated from 1.6 to 6 MeV. The initial radiation dose makes up 300 rad. Radiation rhythm is once per 6 days. The summary therapeutic dose approaches 600-900 rad. The integral radiation dose does not exceed 1.2 R. An operating mockup of betatron with 1 to 3 MeV energy of the extracted beam, 500 rad/min dose rate at the outlet from the emitter at 20 kg mass of the emitter unit and 200x200x150 mm sizes is produced for treatment of dermatoses
