Magnetic feedback control of a Field Reversed Configuration

December 2025 | J.A. Romero | Nuclear Fusion | Paper

The Field Reversed Configuration (FRC) is a highly diamagnetic plasma confinement device used in nuclear fusion research. FRC’s exhibit an internal region of weak magnetic field with ideal conditions to reach the high temperature required to burn high Z aneutronic fuels …

Probing suprathermal electrons in C-2W with x-ray energy spectra

November 2025 | Y. Zhou | Physics of Plasmas | Paper

A silicon drift-detector-based pulse-height x-ray energy spectrometer has been recently deployed on C-2W to investigate the distribution of suprathermal electrons. Measurements from this spectrometer reveal x-ray photons with energies of several kiloelectronvolts …

Directional, joule per steradian THz pulses from multi-joule laser irradiation of wires

July 2025 | G. Bruhaug | Physics of Plasmas | Paper

We report on THz pulses with energy flux exceeding 2.5 J/sr and high directionality, generated from picosecond, joule laser irradiation of
microwires. The impact of wire diameter, length, and laser irradiation orientation is explored …

Generation of field-reversed configurations via neutral beam injection

April 2025 | T. Roche | Nature Communications | Paper

We report evidence of successful generation of field-reversed configuration plasmas by neutral beam injection. This is achieved by trapping the steady state beams in an initial seed plasma, hence providing a direct source of toroidally directed energetic ion current and increase plasma …
