FIELD: physics, possible use in laboratory research, and also during development of new devices for medicine and engineering, where it is needed to eject electron or laser beams in impulse mode.

SUBSTANCE: the essence of method is in using the difference of spreading speeds of gas and electrons. Ejection channel is opened for the time, sufficient for flight of electrons, but insufficient for passage of gas molecules. This allows ejection of short electron beams of any power without loss of their energy with minimal flow of gas in direction of lesser pressure. Claimed device, which realizes the method, does not exhaust all of its capabilities. It is engineered for ejection of electrons from radioactive gas environment with pressure of 1Pa order into vacuum with pressure 10-5-10-6 Pa. Special feature of the method is that on its basis devices may be created for ejection of electron and laser beams without limitation of energy and distortion of their spectrum.

EFFECT: possible creation of devices, which, depending on conditions of operations in conjunction with various methods and means of vacuum and compressor engineering will ensure ejection of electron and laser beams of any energy into space with any pressure.

SUBSTANCE: proposed method for impact compression of material involves use of relativistic vacuum diode that has axisymmetrical vacuum chamber with electricity conducting walls, plasma cathode, and concentrating anode. Target in the form of axisymmetrical part is produced from condensed material and is used at least as part of concentrating anode. The latter is installed in relativistic vacuum diode in a spaced relation to plasma cathode and pulse discharge is applied from power supply to relativistic vacuum diode as electron beam is self-focused on concentrating anode surface. For the purpose use is made of axisymmetrical plasma cathode in the form of conducting rod and butt-end dielectric member coupled to the latter; surface area of conducting rod in dielectric member is larger than maximal cross-sectional area of concentrating anode. Concentrating anode is installed in a spaced relation to plasma cathode so that center of curvature of concentrating anode working surface is disposed within focal length of collectively self-focusing electron beam.

EFFECT: ability of compressing material to superdense condition.
