Enhancement of Ponderomotive End Plugs with Low-Mass Dopants
Ian E. Ochs, Elijah J. Kolmes, Nathaniel J. Fisch
During conventional confinement of a linear plasma using ponderomotive end plugs, a repulsive potential is created at the axial ends by employing a perpendicularly-polarized wave w…
Bremsstrahlung constraints on proton-Boron 11 inertial fusion
I. E. Ochs, E. J. Kolmes, A. S. Glasser +1
Proton-Boron 11 (pB11) fusion is relatively safe and clean, but difficult to use for net power production, since bremsstrahlung radiation tends to radiate away power more quickly t…
Ion Mix Can Invert Centrifugal Confinement
E. J. Kolmes, I. E. Ochs, N. J. Fisch
Centrifugal plasma traps, in which plasma is confined partly by centrifugal forces, represent a possible path to fusion energy production. In centrifugal plasma traps, electric fie…
Efficiency and Physical Limitations of Adiabatic Direct Energy Conversion in Axisymmetric Fields
J. -M. Rax, E. J. Kolmes, N. J. Fisch
We describe and analyze a new class of direct energy conversion schemes based on the adiabatic magnetic drift of charged particles in axisymmetric magnetic fields. The efficiency o…
Coriolis Forces Modify Magnetostatic Ponderomotive Potentials
E. J. Kolmes, N. J. Fisch
It is possible to produce a ponderomotive effect in a plasma system without time-varying fields, if the plasma flows over spatial oscillations in the field. This can be achieved by…
Upper and Lower Bounds on Phase-Space Rearrangements
E. J. Kolmes, N. J. Fisch
Broad classes of plasma phenomena can be understood in terms of phase-space rearrangements. For example, the net effect of a wave-particle interaction may consist of moving populat…
