- Development of indirectly heated cathodes and duoplasmatron type electron feed assemblies is being pursued for use on positive ion sources of neutral beam systems. The cathodes utilize La/sub 2/O/sub 3/ doped molybdenum emission surfaces which supply ionizing electrons for a large rectangular (28 cm. x 60 cm.) magnetic multi-cusp confinement chamber. Single and double electron feed assemblies with different electrode geometries were tested at discharge currents of greater than or equal to 1000 A and pulse lengths of approx. 35 sec. Details of construction and performance results such as plasma uniformity are discussed.
