Fusion, the process that powers the Sun, has great potential to provide clean industrial-scale baseload electrical power, with negligible CO2 emissions and produce little long-term waste. Results from the 500 MW international magnetic confinement experiment ITER will determine the future of fusion energy as a viable alternative source of clean energy. The science and technology of materials under extreme heat loads, and in particular plasma-surface interactions, are critical to the success of plasma fusion sources such as ITER [1] and the ultimate viability of generating fusion power under steady state conditions.20122015-12-08
