  Abstract An account is given of new effective technique of conditioning gaseous insulation of an electrostatic accelerator, primary purifying it from free solid microparticles. The procedure of conditioning continuities to obtaining stable breakdown voltage of high voltage accelerator about 7-8 hours (at value of accelerator tank of 9 cubic meter). Three techniques of check of cleanliness of gaseous insulation or carried out early high voltage experiment are proposed. Conditioning effect keeps after tank opening at a repeated input in tank early purified gas.

  A monitoring system online controls a therapeutic proton beam by measuring a secondary neutron radiation from the beam losses. The system consists of neutron detectors in the transport path passage from Linac to the facility of proton therapy and terminal controller connected to the computer. The neutron detectors measure a level of the secondary neutron radiation in real time along of the transport channel, near the formative elements. The system of the neutron detectors registers temporal variations of the beam intensity in local areas transport medical channel. These changes arise are due to changes in operating mode of the channels or instability of the elements forming the beam. The monitoring system allows to determine a intensity and temporal structure of the therapeutic beam and to detect mode and instability of the formative elements.

  During last couple decades in Russia an interest in the electron-beam sterilization technology has been significantly renewed. The electron beam irradiation occurs at electron energies in the range from 3 up to 10 MeV with dose of 30 kGy. A special research interest is an exploring the possibility to reduce electron energy and dose characteristics upon foods irradiation.
