摘要: The electron distribution function is derived analytically with the linearized Fokker-Planck equation in order to analyze confining potential geometry of mirror ratio R ≪1. magnitude determined by axial loss time (transit time) τ // when longer than coulomb collision τ, on other hand depends mainly \(\tau _{//}\lesssim\tau\) . Especially, it found that does not depend emission rate γ electrons hitting wall as long ≪τ. bounce-averaged nonlinear simulation carried out investigate case =1. temperature T e ⊥ / strongly τ/τ obtained has a tendency decreasing
