Validation of hybrid-PIC simulations for advanced beam-driven FRC modeling

August 2026 | R.E. Groenewald | Nuclear Fusion | Paper

TAE Technologies, Inc. has successfully demonstrated maintenance of a stable field-reversed configuration plasmas through the use of external actuators, which include neutral beam injection, core fueling, and electrode biasing.

A comparison of cusp and mirror topologies for 𝛽 → ∞ magnetic confinement

July 2026 | B.J. Sporer | Journal of Plasmas Physics | Paper

The magnetic confinement topologies potentially capable of macro-stability with core plasma pressure greatly exceeding the vacuum magnetic field pressure (or ‘β → ∞’) are discussed.

Dependence of field-reversed configuration formation in collisional merging experiments on the mirror magnetic field strength

July 2026 | S. Ishiwata (Nihon Univ.) | Journal of Plasmas Physics | Paper

Collisional merging experiments on field-reversed configurations (FRCs) in the FRC amplification via translation–collisional merging (FAT-CM) device have suggested that the mirror magnetic field strength influences the final merged plasma state.

Plasma stability calculations by fast rational approximation

June 2026 | C.K. Lau | Physics of Plasmas | Paper

The recently developed AAA (“adaptive Antoulas–Anderson,” pronounced as “triple-A”) algorithm, which rapidly produces an accurate rational approximation, is an extremely effective numerical technique for the plasma physics community….

Plasma flow and equilibrium in the magnetic nozzle

June 2026 | A. Smolyakov (Univ. of Saskatchewan) | Journal of Plasmas Physics | Paper

Axisymmetric cylindrical configurations of the magnetic field are used to confine and guide plasmas in fusion and electric propulsion devices, where plasma equilibria are established as a balance between plasma pressure, magnetic stress (pressure) …
