Simulation on the Compressed Field-Reversed Configuration with Alpha Particle Self-Heating
Plasma physics and controlled fusion(2019)
摘要
Study on the compression of field-reversed configuration (FRC) by a magnetic-driven solid liner is carried out based on a one-dimensional code. In the investigation, plasma self-heating effect by alpha particles is taken into account. Numerical results show that the self-heating of alpha particles to DT plasma mainly occurs in the vicinity of O-point of the FRC target. The plasma ignition region is divided into two parts: the low-density ignition region near the central axis and the high-density ignition region in the O-point area. Before FRC plasma target expansion, the energy of alpha particles is well confined nearby the O-point by compressed magnetics. The DT plasma volume burning exists in a short time (approximately 0.1 mu s) after a maximum convergence ratio of solid liner and the compressed strong magnetic field degrades the propagation of FRC plasma burning.
