Carl Frederick Weggel — Biographical Profile

Carl Frederick Weggel is a Founding Partner, Chief Scientist, and the original lead designer of the S.M.A.R.T. fusion generator at Kronos Fusion Energy. A persistent advocate of compact, ultra-high-field tokamak architecture for over 50 years, he has contributed to several of the most significant magnetic confinement programs in history.

At MIT between 1973 and 1975, Carl was entrusted by Dr. D. Bruce Montgomery with designing the audacious 14-Tesla toroidal field magnet for the record-setting Alcator "C" tokamak, deriving the magnet's analytic structure via MACSYMA. From 1980 to 1984 he led the Magnet Division at the San Diego startup INESCO, designing the 30-Tesla ohmic heating and 16-Tesla TF magnets for the Riggatron concepts. From 2018 to 2020 he worked alongside his twin brother Robert at Commonwealth Fusion Systems, designing the high-temperature superconducting magnets that drove rapid increases in SPARC's projected fusion gain (Q).

At Kronos Fusion Energy he is driving the technical mission to commercialize an affordable, universally available, aneutronic fusion solution using Deuterium–Helium-3 (D-He3) fuel, advocating direct energy extraction via MHD generators to approach near-100% Carnot efficiency. He is a formally named inventor on the S.M.A.R.T. patent (US12009112B2).
