Passive Superconducting Flux Conservers for Rotating-Magnetic-Field-Driven Field-Reversed Configurations

IC/P4-3 Simulation Studies of Field-Reversed Configurations with Rotating Magnetic Field Current Drive

First results of 3D kinetic simulations of rotating magnetic field (RMF) current drive in fieldreversed configuration (FRC) are presented. Self-consistent hybrid simulations have been performed using the HYM code for evenand odd-parity RMF and different FRC parameters. Simulations show that the RMF pushes the plasma radially inward, resulting in a reduced plasma density outside separatrix. Lowe...

Numerical study of the formation, ion spin-up and nonlinear stability properties of field-reversed configurations

Results of three-dimensional (3D) numerical simulations of field-reversed configurations (FRCs) are presented. The emphasis of this work is on the nonlinear evolution of magnetohydrodynamic (MHD) instabilities in kinetic FRCs and the new FRC formation method by counter-helicity spheromak merging. Kinetic simulations show nonlinear saturation of the n = 1 tilt mode, where n is the toroidal mode ...

Constructing Prime-field Planar Configurations

An infinite class of planar configurations is constructed with distinct prime-field characteristic sets (i.e., configurations represented over a finite set of prime fields but over fields of no other characteristic). It is shown that if p is sufficiently large, then every subset of k primes between p and f(p, k) forms such a set (where f(p, k) = 2[(f-Ak3//2)Bk3/21 for constants A and B). In par...

Forced Topological Nontrivial Field Configurations

The motion of a one-dimensional kink and its energy losses are considered as a model of interaction of nontrivial topological field configurations with external fields. The approach is based on the calculation of the zero modes excitation probability in the external field. We study in the same way the interaction of the t’Hooft–Polyakov monopole with weak external fields. The basic idea is to t...
