Parallel shock-relevant whistler waves and reflected ions driven by a coaxial plasma gun

August 2026 | D.A. Endrizzi (UW-Madison) | Journal of Plasmas Physics | Paper

How do collisionless shocks generate the dissipation necessary to satisfy mass, momentum and energy continuity? For perpendicular shocks, ion reflection and
gyration back to the layer are responsible for dissipation beyond…

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) …
