In-situ analysis allows for rapid optimisation of processing parameters, including the composition of final materials, synthesis times & temperatures and various procedures—foremost being in-situ analysis of Hot Isostatic Pressing (HIP). [Ref. 1]

chemistry or crystal structure. [Ref. 1]

ITER/DEMO designs are both contingent on the successful development of radiation tolerant joining techniques, suitable for operation at elevated temperatures. (+1100oC) [Ref. 4]

Advanced processing can reduce processing temperatures, improve bonding of dissimilar materials, improve stability at

high operating temperatures and allow rapid recovery of radiation damage. [Ref. 3]

Reference to the established ITER timeline illustrates the “realistic” impact of novel research on

future development of fusion technology over the next 20 years. Specifically, the interface analysis

(both theoretically and experimentally) of ITER first wall tiles, would be an achievable goal. Alternately, the broadest scope for novel research would centre

on the development of DEMO test tiles, including the development of advanced materials capable of

operation under higher neutron fluencies and at elevated temperatures (+1100oC)
