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…
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…
Gromov ground state in phase space engineering for fusion energy
Hong Qin, Elijah J. Kolmes, Michael Updike +2
Phase space engineering by RF waves plays important roles in both thermal D-T fusion and non-thermal advanced fuel fusion. But not all phase space manipulation is allowed, certain…
Fueling limits in a cylindrical viscosity-limited reactor
Tal Rubin, Elijah J. Kolmes, Ian E. Ochs +2
Recently, a method to achieve a "natural hot-ion mode" was suggested, by utilizing ion viscous heating in a rotating plasma with a fixed boundary. We explore the steady-state solut…
Current channel evolution in ideal Z pinch for general velocity profiles
Ian E. Ochs, Christine Stollberg, Eyal Kroupp +5
Recent diagnostic advances in gas-puff Z pinches at the Weizmann Institute for the first time allow the reconstruction of the current flow as a function of time and radius. These e…
Maximum-Entropy States for Magnetized Ion Transport
E. J. Kolmes, I. E. Ochs, M. E. Mlodik +1
For a plasma with fixed total energy, number of particles, and momentum, the distribution function that maximizes entropy is a Boltzmann distribution. If, in addition, the rearrang…
Strategies for Advantageous Differential Transport of Ions in Magnetic Fusion Devices
E. J. Kolmes, I. E. Ochs, N. J. Fisch
In a variety of magnetized plasma geometries, it has long been known that highly charged impurities tend to accumulate in regions of higher density. Here, we examine how this "coll…
