“…Research is currently ongoing to determine the best material choices for a number of plasma diagnostics. The technologies Table 1 Summary of some of the major fusion materials achievements accomplished within past 10 years [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] Demonstrated via experiments and MD simulations that fusion defect production 'source term' is similar to that for fission (validates the use of fission reactors for initial testing and screening) [5] Provisional operating windows have been established for all three classes of reduced activation structural materials, based on radiation embrittlement, thermal creep, thermal conductivity, and void swelling considerations [6][7][8][9] (fusion-relevant He/dpa condition still to be probed) Fundamental procedures for fabricating and joining all three classes of structural materials have been established [5,[10][11][12] Development of miniaturized specimen test techniques: evolution from qualitative screening guide to quantitative data generation [5,[13][14][15] Application of Master Curve technique to unify fracture data obtained on different specimen geometries, strain rate, constraint factor, etc. [16] Operating limits for irradiated Cu alloys defined [9,17,18] Determined that permanent radiation-included electrical degradation is not of significant concern for ceramic insulators in next-step machines such as ITER [19,…”
