The closed electron drift plasma accelerator comprises an annular ionization chamber, an acceleration chamber on the same axis as the ionization chamber, an annular anode, a hollow cathode, a first DC voltage source, an annular gas manifold, a magnetic circuit, and magnetic field generators. A coaxial annular coil is placed in the cavity of the ionization chamber, is provided with bias conductive cladding connected, together with the electrically-conductive material of the inside faces of the walls of the ionization chamber, to the positive pole of a second voltage source whose negative pole is connected to the anode, and constitutes an additional magnetic field generator which, together with the other magnetic field generators, forms a magnetic field having a magnetic line of force with an 'X' point corresponding to a magnetic field zero situated between the coaxial annular coil and the anode.
