Multipoles and Surmacs I: Physics

  • F. F. Chen

Abstract

The basic idea in surface magnetic field (surmac) devices1 is to create a magnetic fence surrounding a large volume of reacting plasma (Fig. 1). The field is created by an inner set of conductors, immersed in the plasma, which carry current in the same direction. The return current is carried in an outer set of conductors which lie outside the plasma and need not be inside the vacuum wall. Since the lines of force have alternately good and bad curvature, hydromagnetic instabilities are strongly stabilized by average-minimum-B. The large enclosed volume of field-free plasma cannot emit synchrotron radiation; hence, the major advantage of such devices is purported to be the possibility of burning neutron-free fuels, which require plasma temperatures above 100 keV.
