Laboratory electron beam unit UE-208M was developed, which is fitted with gas-discharge electron guns VTR-300 designed by PJSC «NVO «Chervona Khvilya». In order to produce a block of electron beam heaters UE-208M appropriate technical documentation was developed, components and assemblies of electron beam heater plate, ensuring mechanization and automation of its movement, as well as automated self-contained system of cooling of the electron beam heaters, were manufacture and mounted. Work has been performed on producing ingots of a nickel-based alloy of Ni–Al–Cr system with increased content of alloying elements with a high pressure of Al and Cr vapours. It is found that melting in the developed laboratory electron beam unit UE-208M was performed in a stationary mode, and no significant deviations provoked by intensive vapour flow from the liquid metal mirror at operation of gas-discharge electron guns were found. It is shown that application of gas-discharge electron guns VTR-300 of PJSC «Chervona Khvilya» design as a concentrated energy source, allows performing work on development and optimization of new electron beam technologies of melting refractory and highly-reactive metals, as well as alloys with a high content of volatile alloying elements, while ensuring the high operational reliability.
