AУPT-1M accelerator for radiation technologies

Abstract

AУPT-1M modernized electron accelerator with an accelerating voltage up to 1 MV, a 1-kW electron beam power, and a 100-ns pulse duration is described. As compared to the prototype (УPT-1 accelerator), the layout of assemblies is changed in it, allowing one to place it in rooms with heights up to 2.5 m. It uses Murata capacitors and a ТQPи1–10k/75 thyratron with a cold cathode for switching. The computer-aided parameter-monitoring system is created. A metal-ceramic cathode consisting of several elements with ∼15% nonuniform current density distribution of the electron beam on the exit foil was used to obtain an electron beam with a width of up to 400 mm. The accelerator can be used in radiation technologies in layers with a thickness of up to 0.3 g/cm 2 .
