PLASMA ACCELERATOR Russian patent published in 2019 - IPC H05H5/00 

FIELD: physics.

SUBSTANCE: invention relates to plasma accelerators, particularly, to devices, in which plasma is accelerated under action of field of ponderomotive forces generated in crossed electromagnetic fields created in working volume of device. Such devices are used as space engines and in plasma technologies. Plasma booster comprises current pulse generator, plasma source and spiral electrode with height h_s, the first lead of which is connected to the current pulse generator, and the second one is grounded. Accelerator additionally includes first magnetic core in the form of cylinder with height h₁ and radius R₁, located coaxially inside spiral electrode with radius R_s, permanent magnet in form of hollow cylinder with height h₄, with inner radius R₂ and outer radius R₃, magnetized along height and located coaxially to spiral electrode, second magnetic conductor in form of hollow cylinder with inner radius R₂ and with outer radius R₃, contacting with right end face of permanent magnet and coaxially embracing spiral electrode, third magnetic conductor in form of disc with radius R₃ and height h₃, which contacts its right surface with left ends of permanent magnet and first magnetic conductor, third magnetic conductor has a dielectric input for connecting the first lead of the spiral electrode to the current pulse generator, and said dimensions satisfy the corresponding ratios. Technical result is increase in final speed of generated plasma streams and increase in energy efficiency of plasma accelerator.

EFFECT: as a result, the disclosed device enables generation of neutrons in collision of accelerated deuterium-containing plasma with solid targets containing heavy hydrogen isotopes.
