Effects of Alfven ion cyclotron modes on tandem mirror energy transport

An energy transport model taking into account the effects of Alfven ion cyclotron fluctuations is presented to explain the hot-ion-mode experiments of tandem mirror GAMMA 10. The energy transport equations for the electron and ion including the ion temperature relaxation due to the quasilinear effects of unstable Alfven ion cyclotron modes are derived based on a point model and are solved numerically for the steady state. It is shown that the numerical results obtained from the present model can well explain the experimental results in the hot-ion-mode of GAMMA 10. (author)
