Evaluation of a boron nitride–boron pebble aggregate material for renewable plasma-facing surfaces in magnetic fusion devices

We demonstrate a new renewable boron aggregate material that can withstand heat loads of 40MWm-2 without cooling and featuring low sublimation of below 100Torr-L/s/m2 and sputtering yield of 0.04 from 40eV D, similar to solid boron. The retention of deuterium (D) is 3.2 × 1020D/m2, 200× less than so...
