Deuterium (D) plasma-driven permeation (PDP) experiments for vanadium (V), niobium (Nb) and tantalum (Ta) membranes are performed between 573–873 K in the linear plasma facility PREFACE. The sample te
Abstract: Tokamak plasma facing components have surface roughness that can cause microscopic spatial variations in erosion and deposition and hence influence material migration, erosion lifetime, dust
Time-modulated helium (He) ion energy (e.g. V_Bias = -50 + 25*sin(2*pi*f_RF*t), f_RF = 13.56 MHz) is demonstrated to strongly affect the development of tungsten (W) surface morphology that results fro
