  • The Magnetic Centrifugal Mass Filter concept represents a variation on the plasma centrifuge, with applications that are particularly promising for high-throughput separation of ions with large mass differences. A number of considerations, however, constrain the parameter space in which this device operates best. The rotation speed, magnetic field intensity and ion temperature are constrained by the ion confinement requirements. Collisions must also be large enough to eject ions, but small enough not to eject them too quickly. The existence of favorable regimes meeting these constraints is demonstrated by a single-particle orbit code. As an example of interest, it is shownmore » that separation factors of about 2:3 are achievable in a single pass when separating Aluminum from Strontium ions« less
  • Mass filters using rotating plasmas have been considered for separating nuclear waste and spent nuclear fuel. We propose a new mass filter that utilizes centrifugal and magnetic confinement of ions in a way similar to the asymmetric centrifugal trap. This magnetic centrifugal mass filter is shown to be more proliferation resistant than present technology. This filter is collisional and produces well confined output streams, among other advantages. __________________________________________________
  • Electromagnetic mass separation may be used in studies of nuclear reaction yields and cross sections. The design aspects of the mass separators of continental Europe pertinent to such studies are reviewed, and the causes of material losses are discussed. Some of the studies made with the mass separators are described briefly. The preparation of isotopic targets are considered. (D.L.C.)
