TAE Technologies' research is devoted to producing high temperature, stable, long-lived field-reversed configuration (FRC) plasmas by neutral-beam injection (NBI) and edge biasing/control. The newly constructed C-2W experimental device (also called 'Norman') the world's largest compact-toroid (CT) device, which has several key upgrades from preceding C-2U such as higher input power longer pulse duration of NBI system well installation inner divertors with upgraded electrode biasing systems....
TAE Technologies, Inc. (TAE) is pursuing an alternative approach to magnetically confined fusion, which relies on field-reversed configuration (FRC) plasmas composed of mostly energetic and well-confined particles by means a state-of-the-art tunable energy neutral-beam (NB) injector system. TAE's current experimental device, C-2W (also called 'Norman'), the world's largest compact-toroid device has made significant progress in FRC performance, producing record breaking, high temperature...
