PLASMA ACCELERATOR WITH CLOSED ELECTRON DRIFT Russian patent published in 2009 - IPC H05H1/54 

FIELD: electricity.

SUBSTANCE: plasma accelerator with closed electron drift comprises annular ionisation chamber (2), acceleration chamber (3) coaxial with the ionisation chamber (2), orificed anode (7), hollow cathode (8), first source (82) of direct voltage, annular gas distributor (11), magnetic conductor and magnetic field generators. Ring coaxial coil (24) located in the ionisation chamber (2) cavity is fitted with a conducting shell which is always live and connected to conducting material (9) on the ionisation chamber (2) inner walls (52) and to the positive pole of the second direct voltage source (85); negative pole of the latter source is connected to the anode (7) and forms additional magnetic field generator which produces magnetic field together with other magnetic field generators; the line of force of the above field has point "X" (4) which corresponds to the magnetic field zero and is located between the above ring coaxial coil (24) and the anode (7).

EFFECT: increasing efficiency of active gas ionisation.
