Riassunto:  A hot stable field-reversed configuration (FRC) has been produced in the C-2 experiment by colliding and merging two high-▀ plasmoids preformed by the dynamic version of field-reversed ?-pinch technology. The merging process exhibits the highest poloidal flux amplification obtained in a magnetic confinement system (over tenfold increase). Most of the kinetic energy is converted into thermal energy with total temperature (Ti+Te) exceeding 0.5 keV. The final FRC state exhibits a record FRC lifetime with flux confinement approaching classical values. These findings should have significant implications for fusion research and the physics of magnetic reconnection.
