Pulsed-power driven ion diodes generating quasi-static.-10 MV/cm. l c m scale-length electric fElds 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 time-and space-resolved measurements of the(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)
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)
