Abstract
A solid target boronisation has been performed in the Extrap T2 revers ed field pinch. A boron carbide rod was inserted in the edge plasma du ring hydrogen RFP-discharges. The amount of material released has been measured and the boron carbide film created on the first wall analyse d by scanning Auger spectrometry, X-ray photoelectron spectroscopy, an d ion beam techniques. The article reports on the effect the boronisat ion has upon plasma performance, and contains a quantitative discussio n on the oxygen reduction due to oxidation of boron.
