摘要: Abstract This paper addresses considerations for the radio frequency (RF) heating and current drive actuators on Fusion Nuclear Science Facility (FNSF), focusing Lower Hybrid Range of Frequency (LHRF) Ion Cyclotron (ICRF). FNSF will require long (∼months), steady-state pulses to fulfill its mission high neutron fluence operation qualification fusion nuclear technologies prototypical a power plant. RF are uniquely capable sustaining plasma without requiring large line-of-sight penetrations through breeding blanket, which mitigates impact tritium shielding. The technology generation transmission waves in LHRF ICRF fully mature, however lifetime plasma-facing antenna components reactor environment remains significant gap. Moving location from low field side (LFS) (HFS) tokamak reduces fluxes turbulent energetic particles antenna. Compact HFS designs able fit within blanket sectors with minimal overall dimensions. Material choices structures represent challenge. Existing materials unable simultaneously meet requirements conductivity, strength, temperature, activation. Pathways forward respect development identified.
