Abstract: A device for electron beam processing of materials in space designed for the performance of the technical operations of welding, cutting, heating, filler welding, tube welding, brazing, coating deposition by the method of thermal evaporation of materials under vacuum by an operator in a spacesuit during EVA. The device includes a range of replaceable electron beam handtools, control and power supply modules, connection cables and a module for monitoring the condition of the device which is placed inside the space vehicle.

Abstract: An astronaut's work station for performing experiments or other work in space is designed for use under the conditions of open space on board space vehicles by an astronaut in a spacesuit, using a system of hardware, for instance electron beam, which it accommodates, as well as samples of materials to be worked on, located in a replaceable samples module. The work station is fastened on the outer surface of a long-term orbital space station of the MIR type, or in the cargo bay of a cargo reusable space vehicle of the Shuttle type. The work station comprises a frame containing a base with a foot rail, a hand rail with a holder, a seat with latches for locking-in the replaceable samples module, and an astronaut's sliding foot restraint which moves over the foot rail.
