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….

Characterization of a compact electron cyclotron resonance plasma source under negative DC biasing and microwave plasma cathode operation

February 2026 | Y. Shimabukuro | Plasma Sources Science and Technology | Paper

To realize future long-lifetime negative hydrogen ion sources, two approaches were investigated using a compact coaxial ECR plasma source: direct negative DC biasing and a microwave plasma cathode (MPC) configuration. In noble gases such as argon, …

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) …

Line-Integrated Density From Neutral Beam Shinethrough on a Beam-Driven FRC

June 2026 | C. Exton | HTPD 2026 | Poster

Neutral beam shinethrough detectors on C-2W enable axial FRC density profile reconstruction validated against WarpX simulations, with augmented normalization yielding line-integrated densities consistent with Far-Infrared Interferometry measurements.
