Reconnection during the implosion phase of field reversed configurations

Magnetic field topology changes in Field Reversed Configurations (FRC's) are essential for the formation and containment of the plasma. A significant part of the FRC research program relies upon the idea that a newly formed plasma, formed on open field lines will quickly change field topology before the rapid parallel electron thermal conduction depletes the plasma energy. We have simulated the implosion dynamics of FRC formation using an axisymmetric hybrid model consisting of kinetic ions and finite resistivity fluid electrons. The LASL FRC experiments are well described by our model, which assumes quasineutrality, zero electron inertia, and no electromagnetic radiation
