Title: Particle deconfinement in a bent magnetic mirror

Abstract

Here, coils misalignment in a magnetic mirror can produce additional particle transport. The magnetic field non axi-symmetry is responsible for radial and longitudinal drifts in a way much similar to the neo-classical transport in a tandem mirror cell distorted by end plugs. Accordingly, a regime exhibiting large radial displacements––similar to the resonant regime in tandem mirrors––can be obtained by confining ions azimuthally, for example by means of a properly tuned radial electric field. Because of the mass dependence of the magnetic field non-homogeneity drift velocities, the azimuthal trapping is mass specific, allowing, in principle, the filtering of a specific species based on its mass.

Kinetically Stabilized Axisymmetric Tandem Mirrors: Summary of Studies

Technical Report Post, R F

The path to practical fusion power through plasma confinement in magnetic fields, if it is solely based on the present front-runner, the tokamak, is clearly long, expensive, and arduous. The root causes for this situation lie in the effects of endemic plasma turbulence and in the complexity the tokamak's ''closed'' field geometry. The studies carried out in the investigations described in the attached reports are aimed at finding an approach that does not suffer from these problems. This goal is to be achieved by employing an axisymmetric ''open'' magnetic field geometry, i.e. one generated by a linear array of circularmore »« less

Theoretical studies in tandem mirror physics

Conference Cohen, R H ; Auerbach, S P ; Baldwin, D E ; ...

Recent developments in six areas of tandem-mirror theory are explored. Specifically, FLR terms (including electric-field drift) have been added to our 3-D paraxial MHD equilibrium code. Our low-frequency MHD stability analysis with FLR, which previously included only m/sub theta/ = 1 rigid perturbations, has been extended to incorporate moderate m/sub theta/, rotational drive, finite-beta effects on wall stabilization, and the well-digging effect of energetic electrons by using three computational techniques. In addition, we have examined the microstability of relativistic electrons with a loss-cone distribution, emphasizing the whistler and cyclotron-maser instabilities. We have also studied techniques for controlling radial transport, includingmore »« less

Radial confinement of central cell plasma in tandem mirrors

Thesis/Dissertation Lao, L L

The single particle guiding center orbit analysis is carried out both numerically and analytically. The guiding center orbit can be characterized by the amount of the azimuthal drift, ..delta..theta, of a particle in one bounce through the central cell. It is demonstrated numerically using the magnetic field geometry and plasma parameters of the Wisconsin tandem device PHAEDRUS,, that if ..delta..theta << 1, the particle drift surfaces are circular when the flux tubes in the plugs are joined orthogonally to each other. The radial losses of particle and energy are studied in the fluid approximation. A set of transport equations aremore »« less
