Small high-power electron-beam device for manufacturing work and physical experiments in space
Abstract
The paper examines the design of a high-power electron-beam device with an autonomous dc-voltage source that was used for electron-beam injection in the Araks experiment and can be used for electron-beam welding in the context of space manufacturing. The design principle is described, and the specifications of the main units of the device are presented, including the units responsible for the conversion of the dc voltage of the primary source to ac voltage, the rectification of the high voltage, and electron-beam injection. Also considered are the units for electron-beam control and for the conversion of the telemetered parameters of the device into analog voltage. A block diagram is presented along with an oscillogram of the beam current and a cyclogram of device operation.
