Compact torus experiments and theory

  title={Compact torus experiments and theory},
  author={William T. Armstrong and D. C. Barnes and R. R. Bartsch},
Two types of compact toroids have been studied: spheromaks and field-reversed configurations (FRC). Spheromaks, which contain both toroidal and poloidal fields, have been formed with a magnetized coaxial injector and trapped in both prolate and oblate flux conservers. As expected from theory, the prolate configuration always tilts, but the oblate configuration can be made stable even in the presence of a guide field. Observations include 150..mu..s lifetimes, approx. 10/sup 14/ cm/sup -3/, and… CONTINUE READING
