Increased p-11B fusion reaction rate through fast-ion acceleration by ion cyclotron range of frequencies heating in LHD

February 2026 | S. Kamio | Nuclear Fusion | Paper

Among various advanced fuel cycles, proton-boron-11 (p-11B) fusion has attracted renewed interest as a potentially clean and sustainable fusion energy source.
This aneutronic fusion concept has long been envisioned as an ultimate cleaner fusion reactor scheme…

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 …

Advanced neutral beam injection in a field-reserved configuration plasma

September 2025 | J.B. Titus | Nuclear Fusion | Paper

Neutral beam injection has been shown to create field-reversed configuration plasmas on C-2W. Recent advances in optimization and control of eight neutral beam injectors help deliver customized current drive for a plethora of plasma regimes.
