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 …

A verification study of a semi-implicit energy-conserving electrostatic particle-in-cell algorithm is presented. The algorithm relaxes the time-step and mesh-size constraints that require resolution of the plasma period and Debye length associated with traditional explicit momentum-conserving particle-in-cell algorithms

Fast ions confined by the FRC likely cause electrons in the FR to heat up and emit X-rays. We plan to identify the exact location of electron heating by improving the spatial resolution of the X-ray diagnostic. The X-ray diagnostic will also be used to study electron heating induced by an Electron Cyclotron Resonance…
