Summary

Impurity ions affect fusion plasma performance by altering confinement, and their behavior must be studied in detail. This thesis investigates problems related to impurities, including collisional damping of zonal flows in tokamaks and impurity transport driven by microturbulence. Heavy, highly charged impurities significantly influence the development of zonal flows, leading to faster damping. A semi-analytical model is presented to describe impurity fluxes and stability boundaries, showing good agreement with numerical simulations.
