In this work we investigate the ionization by proton impact, and photo ionization, involving highly charged ions of W, in particular the Ne-like  W64+ and Na-like W63+ which are more likely to appear in ITER plasma. Total cross sections are calculated in the continuum-distorted- wave-eikonal-initial-state (CDW-EIS) approximation for ion-impact, whiletwo completely different methods are used for photoionization: a  perturbative dipolar aproach and the recently introduced Sturmian model.
