Abstract

Enhancement of the bremsstrahlung X-ray radiation (BSXR) power generated by the high-current relativistic electron beam (REB) of a pulsed direct-action accelerator TEMP-B is being curried out to use in particular for studying the radiation resistance of walls material of radioactive waste containers. For this the magnetic field in which REB is transported in the drift chamber is taken higher at some distance before the converter to provide REB diameter on the converter the same as in the drift chamber. Scheme of power supply and creation of the required magnetic field for the REB current transportation through the whole distance from the diode to the converter is developed. Higher BSXR dose per REB current pulse at the same energy resource is obtained.
