Abstract

Boronisation, i.e. plasma induced deposition of amorphous boron containing carbon films a-C/B:H on all inner surfaces of fusion devices, has proved to be a powerful conditioning method to achieve very pure fusion plasmas. The use of the highly toxic and explosive gas diborane (B(2)H(6)) in conventional boronisation requires considerable precautions for safe handling. A new technique for boronisation is reported, using less hazardous organic boron compounds, namely borontrimethyl B(CH(3))(3) and borontriethyl B(C(2)H(5))(3). First results indicate that films produced from borontrimethyl have a similar performance in fusion devices to that of layers produced in the conventional way. The new technique thus offers an easier and more convenient method for the boronisation of surfaces.
