Asymptotic behavior of the shear flow reactivity enhancement effect

Henry Fetsch, Nathaniel J. Fisch

Fusion reactivity is enhanced in the vicinity of strongly sheared flow due to the tendency of fast ions near the Gamow peak to travel long distances between collisions, thereby som…

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…

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…

Energy Spectrum of Lost Alpha Particles in Magnetic Mirror Confinement

Alejandro Mesa Dame, Ian E. Ochs, Nathaniel J. Fisch

In a magnetic mirror fusion reactor, capturing the energy of fusion-produced alpha particles is essential to sustaining the reaction. However, since alpha particles are born at ene…

Preventing ash from poisoning proton-boron 11 fusion plasmas

Ian E. Ochs, Elijah J. Kolmes, Nathaniel J. Fisch

Proton-Boron 11 (pB11) fusion is safe and clean, but also difficult to harness for breakeven power production. Particularly deleterious are fusion-born alpha particles, which massi…
