Observation of superdense megavolt ion beams in a long-pulse magnetically insulated diode

Technical Report ·
OSTI ID:7208313
In microsecond-megavolt-pulse experiments with a magnetically insulated diode, high-energy ion beam densities of up to 300 A/cm/sup 2/ were obtained which are superdense (i.e. above the Child-Langmuir limit) by an order of magnitude. Ion pulse durations of up to 1 ..mu..sec resulted in large time-integrated ion yields: up to 120 ..mu..Asec/cm/sup 2/ (75 ..mu..Asec/cm/sup 2/ of protons) per pulse which may be sufficient for the generation of field-reversing ion rings. Using conducting anodes, megavolt insulation times in the microsecond range were observed for gap spacings of 1.2 to 1.7 cm.
