Pulsed-power driven ion diodes generating quasi-static, -10 MV/cm, 1-cm scale-length electric fields are used to accelerate lithium ion beams for inertial confinement fusion applications. Atomic emission spectroscopy measurements contribute to understanding the acceleration gap physics, in particular by combining timeand space-resolved measurements of the(More)
The ZR project [1] to refurbish the Z accelerator at Sandia National Laboratories [2] is scheduled for completion in FY06. An important factor for the success of ZR is limiting current losses in the vacuum section. On Z today, late-time losses of 5 – 10% are observed, which are known to occur in the post-hole convolute region. The most direct way to(More)
RECEI 3UH 3 0 Intense ion beams may be the best option for an Inertial Fusion Energy (IFE) driver. While light ions may be the long-term pulsed power approach to IFE, the current economic climate is such that there is no urgency in developing fusion energy sources. Research on light ion beams at Sandia will be suspended at the end of this fiscal year in(More)
It is desirable to optimize (minimizing both the inductance and electron flow) the magnetically insulated vacuum sections of low impedance pulsed-power drivers. The goal of low inductance is understandable from basic efficiency arguments. The goal of low electron flow results from two observations: (1) flowing electrons generally do not deliver energy to(More)
Z-Pinch Inertial Fusion Energy (Z-IFE) complements and extends the single-shot zpinch fusion program on Z to a repetitive, high-yield, power plant scenario that can be used for the production of electricity, transmutation of nuclear waste, and hydrogen production, all with no CO2 production and no long-lived radioactive nuclear waste. The Z-IFE concept uses(More)
