Production and characterization of ion beams from magnetically insulated diodes
Abstract
The operation of magnetically insulated diodes and the characteristics of the resulting ion beams were investigated using two pulsed power generators, LYNX at the 10 to the 9th power level, and Neptune at the 10 to the 10th power. LYNX is a small magnetically insulated diode driven directly by a Marx bank. By changing the materialused as the surface flashover ion souce, the majority ion species generated by the diode could be chosen. Ion beams produced so far by this device are: protons, lithium, boron, carbon, sodium, strontium, and barium. Typical beam parameters for the ion beams are peak energies of 300 keV, current densities of 40-60 A/square cm and pulse durations of 300 to 400 nsec. The ion beam uniformity, divergence, and reproducibility were shown to be a function of the surface flashover source geometry. Finally, the LYNX ion beam was also used to anneal silicon crystals and other materials science experiments.
