Batrakov O. Radiation-beam technological complex based on the high-current pulsed relativistic electron beam accelerators

For the first time a new approach is proposed for increasing the power of concentrated energy fluxes and X-ray bremsstrahlung on the REB accelerators with constant margin of energy. The approach consists in investigating the complex effect of the developed vacuum diode elements in the field of REB production and transport, using a combined magnetic system with a magnetic field strength increased to 1,7?106 А/m, using an oil-less cryogenic vacuum system with an operating residual gas pressure in the accelerator vacuum diode at the level of 1·10 -4 Pа and developed XRB generator, as well as, designing on the base of the foregoing of a complex method for increasing the above-mentioned parameters. The radiation beam system was developed for the first time. It is characterized by two irradiative factors: concentrated energy flows (electron beams 0,35<Еb<0,75 МеВ, Іb?21 кА) and the intense slowing-down X-radiation with the exposure dose of 9100P/ pulse without the induced activityFor the first time due to the use of a cryogenic condensation-adsorption pump (developed and patented by the dissertation's author) a cryogenic oil-less operation mode of the vacuum system in the REB accelerator "Temp-B" is realized that permits to increase the power REB and its duration to 1,5 µs. It has been established that the sleeve cathodes should be used to increase a dose of slowing-down X-ray. These cathodes increase a dose of slowing-down X-ray by 70% along the accelerator axis. The diagrams showing the direction of action of slowing-down X-radiation were obtained for the developed intense sources of slowing-down X-radiation.
