Fast-Ion Axial Bounce Resonance in a Linear Magnetic Fusion Device

May 2026 | S. Karbashewski | Physical Review Letters | Paper

We report observations of an energetic-particle mode (EPM) in a linear plasma device that corresponds to an axial bounce resonance of fast ions sourced from neutral-beam injection (NBI). In our experiment, novel dynamic shaping of a magnetic mirror field reduces the distance …

Verification of an energy-conserving semi-implicit electrostatic particle-in-cell scheme for modeling high-density plasma at scale

May 2026 | R.M. Hedlof (SNL) | Physics of Plasmas | Paper

A verification study of a semi-implicit energy-conserving electrostatic particle-in-cell algorithm is presented. The algorithm relaxes the time-step and mesh-size constraints that require resolution of the plasma period and Debye length associated with traditional explicit momentum-conserving particle-in-cell algorithms

Stability of High Beta Plasma Calculations by Monte Carlo Orbit Integration

November 2025 | C. Lau | APS DPP 2025 | Poster

CLAUS is a new non-variational eigenvalue solver, which is a modern implementation of the dispersion functional approach based on the Vlasov-Maxwell model and developed specifically for high-𝛽 plasmas with analytically intractable particle orbits.

Electrode Bias Propagation in the C-2W Fusion Research Device

November 2025 | A. Bondarenko | APS DPP 2025 | Poster

TAE Technologies’ fifth-generation fusion research device C-2W1 utilizes neutral beam injection and edge biasing to sustain long-lived, stable field reversed configuration (FRC)2 plasma embedded within a magnetic mirror.

Experimental and Theoretical Progress on Beam-Driven FRCs in the C-2W Device

November 2025 | M. Nations | APS DPP 2025 | Poster

TAE Technologies’ C-2W device has achieved stable, beam-driven Field-Reversed Configurations (FRCs) maintained for up to 40 ms. Recent advances include real-time plasma control, enhanced fueling via pellets and compact toroids, and the commissioning of new cyclotron resonance heating systems.
