OSTI ID:5785157
Low Z boron coatings have been tested for stability under simulated fusion reactor conditions including simultaneous temperature cycling and ion implantation from the /sup 10/B (n,..cap alpha..)/sup 7/Li reaction. Boron coatings several microns thick, produced by vacuum evaporation onto heated titanium substrates, exhibited reasonable stability after doses of 3.8 x 10/sup 18/ ..cap alpha../cm/sup 2/ and 1320 temperature cycles from 165 to 490/sup 0/C. These conditions correspond to exposures at the first wall of the fusion reactor, ranging from a few weeks to about 6 months, depending on the reactor design.
