In order to determine if a simple magnetic cusp, which is axisymmetric, can be used as an end cell (anchor and plug) for a tandem mirror reactor, a large (50 cm) bore, superconducting, magnetic cusp is being built at the University of Missouri. Prior to the construction of this device, an approximately half scale normal magnetic cusp was built, and experiments involving ECRF heating were conducted, to better establish the design conditions for the large, high field (4-Tesla) cusp.
