Analytical model for collisional impurity transport in tokamaks at arbitrary collisionality

Abstract The physics governing the collisional transport of impurities in tokamak plasmas can change significantly depending on four main parameters, namely collisionality, impurity charge and mass, trapped particle fraction, which vary widely from core to edge a fusion device. We present an analytical model for with consistent dependence broad scans these showing good agreement drift-kinetic code NEO. Radial profiles fluxes are calculated different species using ASDEX Upgrade experimental as well ITER simulated profiles, they also compared This is suited fast integrated modelling applications due its low computational cost.
