Practical Considerations in Realizing a Magnetic C entrifugal Mass Filter
Authors: Renaud Gueroult and Nathaniel J. Fisch
Abstract:
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 shown that separation factors of about 2:3 are achievable in a single pass when
separating Aluminum from Strontium ions.
