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…
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…
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…
Restoring momentum conservation to magnetized quasilinear diffusion
I. E. Ochs
Wave interactions with magnetized particles underly many plasma heating and current drive technologies. Typically, these interactions are modeled by bounce-averaging the quasilinea…
Approximating the Particle Distribution in Rotating and Tandem Mirror Traps
Greta X. Li, Elijah J. Kolmes, Ian E. Ochs +1
Steady state distribution functions can be used to calculate stability conditions for modes, radiation energy losses, and particle loss rates. Heuristic analytic approximations to…
Bounce-Averaged Theory In Arbitrary Multi-Well Plasmas: Solution Domains and the Graph Structure of their Connections
I. E. Ochs
Bounce-averaged theories provide a framework for simulating relatively slow processes, such as collisional transport and quasilinear diffusion, by averaging these processes over th…
