Abstract

Summary form only given. A cylindrical version of the single grid inertial electrostatic confinement (IEC) device (termed the C-device) has been developed for use as a 2.5-MeV D-D fusion neutron source for neutron activation analysis. The c-device employs a hollow-tube type cathode with similar anodes backed up by "reflector" dishes. The resulting discharge differs from a conventional hollow cathode discharge, by creating an explicit ion beam which is "pinched" in the cathode region. Resulting fusion reactions generate /spl sim/10/sup 6/ neutron/s. A pulsed version is under development for applications requiring higher fluxes. Several pulsing techniques are under study, including an electron emitter (e-emitter) assisted discharge in a thorated tungsten wire emitter located behind a slotted area in the reflector dishes.
