摘要：A high-intensity pulsed ion beam (HIPIB) technique is applied to heat flux testing of plasma facing materials for fusion experiment. The HIPIB is generated at a relatively stable power density up to 10(8) W/cm(2), which covers a heat flux parameter of up to several hundreds MW m(-2) s(1/2). Surface morphology and weight loss are examined for doped and coated graphite with HIPIB exposure of 280 MW m(-2) s(1/2), being of the same order of thermal loads during off-normal events in future fusion reactors. The work demonstrates a first example utilizing the HIPIB technique to study thermal response of plasma facing materials under fusion relevant thermal loads.
