Abstract Text:
We report on 3-D, fully electromagnetic kinetic modeling of the field-reversed-configuration (FRC) formation by odd-parity rotating magnetic fields (RMFo) in the PFRC-1 and upgraded PFRC-2. The simulation model includes the Lorentz force, atomic physics effects, externally applied time-varying electromagnetic fields, and material boundary conditions. The new simulations use the new magnetic-implicit (MI) energy-conserving technique that permits under-resolution of the electron cyclotron frequency. The MI results are first benchmarked against those published of PFRC-1 field reversal using the energy-conserving-explicit technique. We then report on initial simulations of PFRC-2. The PFRC-2 machine is 8x larger in volume with 10x larger Bz field, higher power RMFo, and roughly 10x larger plasma density. We will discuss the relative computational speed and accuracy of the new numerical technique in the dynamic FRC conditions.
