Presenter: Hiroshi Gota IAEA FEC2020 (virtual) – May 12, 2021

Key Accomplishments on C-2W:

• Established reliable beam-driven high-βfield-reversed configurations (FRCs)

• Demonstrated FRC sustainment up to 30 msvia neutral-beam injection and edge biasing (limited by the energy storage on-site)

• Achieved total plasma temperature >3 keV

• Extended operational boundary, S*/E >3 (historical limit ~3), without tilting FRC

• Implemented reliable machine/FRCoptimizations, using advanced Optometrist Algorithm and active feedback plasma control systems

• Continued successful external collaborations
