Effects of Yushmanov-Trapped Particles and Anisotropy of Velocity Distribution on the Potential Formation in the End Region of a Tandem Mirror

概要

論文の詳細を見る
Theoretical analyses are made on the structure of the potential distribution along open field lines in a plasma where the velocity distributions of particles are modified from Maxwellian to include Yushmanov-trapped components and temperature anisotropy. The considered particle species are warm electrons and ions flowing out of the system, secondary electrons flowing backward, and Yushmanov electrons trapped between a stronger side of the magnetic field and reflecting potential. The analyses show systematic variations in the potential profile with the change in the temperature anisotropy and the abundance of the Yushmanov-trapped particles. Moreover, the analyses predict measurable feed-back effects to the local heating for the plasma Control.
