UNCLASSIFIED//FOA OFFI€1Ak Wlili ()NL¥ Table 5: Emerging Technologies Technology Application Supports Status High-temperature plasma containers Aiding confinement, supporting fusion architecture, surviving sustained reactions / lifetime ALL Need lightweight materials to withstand the fusion-burning environments repeatedly. Plasma injection schemes To supply plasma for startup, sustained reactions, symmetry, energy deposition ALL There needs to be an efficient and effective way to get fuel stored, delivered, and ignited. Stable magnet configurations Needed for sufficient confinement times / ignition densities, minimize instabilities, optimal propulsion profiles CBFR, IEC, DPF Some experiments are in progress, but designs will evolve as limitations are encountered. Lightweight high- strength magnets Needed for aerospace application, cost effect tive launch and deploy ment, thermal tolerance, superconductivity at workable temperatures. IEC, CBFR High-temperature ceramics still need to be molded to a launch and deployment survivable standard. Much material science and testing are needed. Propulsion nozzles for efficient energy channeling Optimizes efficiency of propulsion, supports direct conversion, support viable missions ALL This is the result of current studies and is specific to design limitations and support. Lightweight particle accelerators for aerospace applications For particle beam injection, energy deposition, confinement, and fusion support IEC, CBFR Most experiments are currently ground oriented - need to transition to flight. Direct-energy conversion schemes Needed for high Q and efficient propulsion schemes ALL Currently under study for recovering energy from charged particle beams, magnetic fields, thermal recycling. High-energy density batteries and supercapacitors Needed for energy storage and startup operations ALL Application of nano materials and thin film manufacturing have accelerated development Fuel storage systems Cryogenic H2, D2 and B gas storage ALL Development of solid fuel storage will reduce mass and costs.
