Scarsbrook}, title = {Thermal shock resistance of thick boron-doped diamond under extreme heat loads}, abstract = {Thick free-standing boron-doped diamonds were prepared by microwave plasma assisted chemical vapour deposition. Samples with a final thickness close to 5 mm and with lateral dimensions 25 x 25 mm were produced. The thermal shock resistance of the material was tested by exposure in the JUDITH electron gun to reproduce the conditions expected in a fusion reactor during plasma instabilities. Boron-doped diamond is shown to exhibit thermal shock resistance far better than current material of choice for a fusion reactor like tungsten, with no surface damage after exposure to 100 cycles at 2.5 GW m(-2) for 5 ms. }, year = {2011}, journal = {Nuclear Fusion}, volume = {51}, number = {5}, pages = {052001}, month = {May}, isbn = {0029-5515}, doi = {10.1088/0029-5515/51/5/052001}, note = {ISI Document Delivery No.: 755MUTimes Cited: 0Cited Reference Count: 17}, language = {English}, }
