Effective Gyro Hole Loss Radius and Diamagnetic Limit in Polywell (Tradename)Systems

摘要

Electron gyromagnetic motion parallel to the external surface can (and will)produce internal currents that create magnetic fields of opposite sign to that of the externally-driven cusp field. Only those electrons whose gyro orbits encircle the cusp axis have any net effect on this process. The volume of the diamagnetically-effective electrons is bounded roughly by a torus of major and minor radius equal to the gyro radius in the effective cusp field.
