Behaviour of boron-doped graphites, plasma-sprayed B4C, and of a-C/B:H as plasma-facing materials
A variety of boron/carbon materials with different boron/carbon (B/C) ratios were included in the research programme which this paper documents. Emphasis was placed not only on the characterisation of the material, but also on its thermomechanical performance under fusion-relevant conditions. Characterisation methods applied included ceramography, optical and scanning electron microscopy, image analysis, and microprobe and X-ray diffraction analyses. The thermomechanical performance of the different boron/carbon materials was investigated in two different high heat flux facilities: (i) in the electron and ion beam facilities at Forschungszentrum Jülich to evaluate performance under normal operation heat loads and (ii) in the Japan Atomic Energy Research Institute Electron Beam Irradiation Stand (JEBIS) to investigate behaviour under short high-energy beam pulses (disruption simulation).
