Particle distribution function in plasma and the self-consistent magnetic field

J. Lacina1966年被引用 1Nuclear FusionIF 3出版社

The equilibrium configuration of plasma (the stationary distribution function of charged particles) and of the self-consistent magnetic field is determined on the basis of the first integrals of motion. A detailed analysis is made of the mutual relation between the resultant magnetic field B and the dependence of the distribution function on the integrals of motion; the necessary and sufficient conditions which must be satisfied by the distribution function with a minimum-B field are obtained. For the configuration with a minimum in B on the axis of symmetry, the function F(pφ) must decrease rapidly with increasing pφ in the vicinity of pφ = 0. Accordingly, the number of particles must have a maximum for particles that perform Larmor gyration around the axis (epφ < 0), and the number of particles intersecting the axis (pφ = 0), must be non-zero

プラズマの平衡配位(荷電粒子の定常分布関数)と自己無撞着な磁場の平衡配位は、運動の第一積分に基づいて決定される。結果として生じる磁場Bと、分布関数の積分への依存性との間の相互関係について詳細な解析が行われる。最小B磁場に対する分布関数が満たさなければならない必要十分条件が得られる。対称軸上でBが最小となる配位に対しては、関数F(pφ)はpφ = 0の近傍でpφの増加とともに急速に減少しなければならない。したがって、軸の周りをラーモア回転する粒子(epφ < 0)に対して粒子数は最大でなければならず、軸と交差する粒子(pφ = 0)の数は非零でなければならない。
