Abstract TAE Technologies’ fifth-generation fusion device, C-2W (also called ‘Norman’), is the world’s largest compact-toroid device and has made significant progress in field-reversed configuration (FRC) plasma performance. produces record breaking, macroscopically stable, high-temperature advanced beam-driven FRC plasmas, dominated by injected fast particles sustained steady state, which primarily limited neutral-beam (NB) pulse duration. The NB power supply system recently been upgraded...
The advanced beam-driven FRC is a Field Reversed Configuration (FRC) with the addition of neutral beam (NB) injection, electrode biasing, and magnetic expander divertors. resulting configuration has novel features that make it necessary to revisit many key results in theory. Three these include (i) large energetic ion population, (ii) in-principle capability adjust electric field rotation profiles, (iii) combination electrostatic confinement electrons SOL. In some fueling scenarios electron...
The field reversed configuration (FRC), such as studied in the C-2W experiment at TAE Technologies, is an attractive candidate for realizing a nuclear fusion reactor. In FRC, kinetic ion effects play majority role macroscopic stability, which allows global stability studies to make use of fluid-kinetic hybrid (also referred Ohm's law) models wherein ions are treated kinetically while electrons fluid. development and validation particle-in-cell algorithm Exascale Computing Project code WarpX...
The electron dynamics of laser wakefield acceleration (LWFA) is examined in the high-density regime using particle-in-cell simulations. These simulations model source as a target carbon nanotubes. Carbon nanotubes readily allow access to near-critical densities and may have other advantageous properties for potential medical applications acceleration. In density regime, electrons are accelerated by ponderomotive force followed sheath formation, resulting flow bulk electrons. This behavior...
The Alfvén-ion cyclotron (AIC) mode is an instability that can be driven in magnetized plasmas with anisotropic pressure. Its chief deleterious effect the driving of enhanced pitch-angle scattering ions. Although AIC has been observed several mirror devices, it not yet FRC devices developed by TAE Technologies [H. Gota et al., Nucl. Fusion 61, 106039 (2021)]. Previous theoretical work [T. Tajima Phys. Rev. Lett. 39, 201 (1977)] suggested sufficient axial inhomogeneity, quantified a critical...
In the scrape-off-layer (SOL) of a field-reversed configuration, neutral beam injection can drive modes in vicinity ion-cyclotron frequency. Depending on their properties, these have differing macroscopic effects plasma. Using particle-in-cell simulations and semi-analytical methods, this work examines properties various categories that be excited SOL environment, taking an ion beta 10%. Propagation angle are scanned from 0° to 90° with respect external magnetic field. The linear physics is...
Recent developments in fiber lasers and nanomaterials have allowed the possibility of using laser wakefield acceleration (LWFA) as source low-energy electron radiation for endoscopic intraoperative brachytherapy, a technique which sources cancer treatment are brought directly to affected tissues, avoiding collateral damage intervening tissues. To this end, dynamics LWFA is examined high-density regime. In near-critical density regime, electrons accelerated by ponderomotive force followed an...
