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.

碰撞对静电模式驱动的杂质传输的影响

高电荷、碰撞杂质物质的湍流引起的准线性粒子通量是从静电陀螺动力学方程计算的，包括与体离子和杂质本身的碰撞。该方程通过杂质电荷数的幂次方展开求解 $Z$ . 在这种形式中，碰撞算子仅通过杂质在平行于磁场的方向上的动力学来影响杂质通量。在与反应堆相关的碰撞中，平行动力学主要由平行电场主导，并且碰撞对高电荷碰撞杂质的湍流粒子通量影响较小。
