Electrons quench ion tails during evaporative cooling in hot ion mode plasmas
Eric Palmerduca, Hong Qin, Nathaniel J. Fisch
It is shown how evaporative cooling in hot plasma is essentially different from evaporative cooling in other media, such as neutral gases or Bose-Einstein condensates. The fundamen…

Thresholdless IBW Emission and Alpha-to-Thermal-Ion Energy Channeling via Pole Resonance of Fusion-Product Ions
Hong Qin, Nathaniel J. Fisch
Fusion reactions can release a substantial fraction, and in aneutronic reactions nearly all, of their energy as the kinetic energy of fusion-product ions. In magnetized plasmas, th…

On Minimizing Phase Space Energies
Michael Updike, Nicholas Bohlsen, Hong Qin +1
A primary technical challenge for harnessing fusion energy is to control and extract energy from a non-thermal distribution of charged particles. The fact that phase space evolves…
