ABSTRACT:
A band gap mass filter for separating particles of mass (M1) from particles of mass (M2) in a multi-species plasma includes a chamber defining an axis. Coils around the chamber generate an axially aligned magnetic field defined (B=B0+B1sin ωt), with an antenna generating the sinusoidal component (B1sin ωt) to induce an azimuthal electric field (Eθ) in the chamber. The resultant crossed electric and magnetic fields place particles M2on unconfined orbits for collection inside the chamber, and pass the particles M1through said chamber for separation from the particles M2. Unconfined orbits for particles M2are determined according to an α-β plot(α=Ω02+Ω12/24⁢ω2,and⁢ ⁢β=Ω0⁢Ω18⁢ω2),where Ω0is the cyclotron frequency for particles with mass/charge ratio M, and wherein Ω0=B0/M and Ω1=B1/M.
