Development of alternative methods for surface thermal loading simulation

Experience on operation and development of alternative ways for thermal loa ding simulation for plasma facing components (PFC) tests and other fusion t echnology experiments are described in the article. These methods are based on a simple heat transfer through soft carbon-based contacting interlayer. Nevertheless, the following specific heat fluxes on surfaces of tested moc k-ups were attained: up to 40 MW m(-2) at short-time regime (several min, 30 min); up to 10-12 MW m(-2) - at long-term (hundreds of h) non-stop or in cycling regimes. Three experimental rigs and one completely arranged facility utilising ment ioned method of on-surface thermal load creation, built in Efremov Institut e, are described in the article.
