Exploding metal film active anode source experiments on the LION extractor ion diode

Summary Form only given, as follows. Results obtained with an extractor-geometry magnetically insulated ion diode on the 0.5 TW LION accelerator are reported. Experiments with an exploding metal film active anode plasma source (EMFAAPS) have shown that intense beams with significantly improved turn-on time compared to epoxy-filled-groove anodes can be produced. A new geometry, in which a plasma switch is used to provide the current path that explodes the thin-film anode, has improved the ion efficiency (to typically 70%) compared with the previous scheme in which an electron collector on the anode provided this current. Leakage electron current is reduced when no collector is used.<>
