论文摘要
湍流诱导的高电荷碰撞杂质物种的准线性颗粒通量是根据静电陀螺仪方程计算得出的，包括与散装离子和杂质本身的碰撞。该方程是通过扩展杂质费用数字$ z $来解决的。在这种形式主义中，碰撞算子仅通过与磁场平行的方向杂质的动力学影响杂质通量。在反应器相关的碰撞时，平行动力学由平行的电场主导，碰撞对高电荷，碰撞杂质的湍流磁通量有很小的影响。
The turbulence-induced quasi-linear particle flux of a highly-charged, collisional impurity species is calculated from the electrostatic gyrokinetic equation including collisions with the bulk ions and the impurities themselves. The equation is solved by an expansion in powers of the impurity charge number $Z$. In this formalism, the collision operator only affects the impurity flux through the dynamics of the impurities in the direction parallel to the magnetic field. At reactor-relevant collisionality, the parallel dynamics is dominated by the parallel electric field, and collisions have a minor effect on the turbulent particle flux of highly-charged, collisional impurities.
