A plasma filter for separating particles includes a hollow semi-cylindrical chamber that is enclosed by a wall. At least one plasma source is mounted in the chamber between the longitudinal axis of the chamber and the wall for generating a multi-species plasma containing light mass particles (M1) and heavy mass particles (M2). A magnetic coil is used to generate a magnetic field, Bz, in the chamber that is aligned parallel to the longitudinal axis, and electrodes at each end of the chamber generate an electric field, Er, in the chamber that is oriented perpendicular to the longitudinal axis. These crossed electric and magnetic fields rotate the multi-species plasma on a curved path around the longitudinal axis, and in a plane substantially perpendicular to the longitudinal axis, to separate M1 from M2. Thus, the wall of the chamber acts as a circumferential collector for collecting the heavy mass particles (M2), and a radial collector which is located at an azimuthal angle beta from the plasma source, and which extends radially between the circumferential collector and the longitudinal axis, is used for collecting the light mass particles (M1).
