Centrifugal filter for multi-species plasma |
摘要 |
A centrifugal filter for separating low-mass particles from high-mass particles in a rotating multi-species plasma includes a pair of annular shaped coaxially oriented conductors. The conductors are both aligned along a central axis and are spaced apart to create a plasma passageway between them. In this configuration, the conductors generate respective magnetic field components which interact to create a magnetic field having an increased magnitude in the passageway and a decreased magnitude along the central axis. The filter also includes an electric field which has a positive potential along the central axis and a decreasing potential in an outwardly radial direction from the central axis. Specifically, this electric field is crossed with the magnetic field in the passageway to confine low-mass particles in the passageway and to eject high-mass particles from the passageway. The particular configuration of the magnetic field for these crossed fields improves efficacy in the separation of the high-mass from the low-mass particles by requiring greater forces for the ejection of particles from the plasma.
