ABSTRACT The authors have designed and tested a 10 nH, 1.5 m radius vacuum
section for the Z accelerator. The vacuum section consists of four
vacuum flares, four conical 1.3 m radius magnetically-insulated
transmission lines (MITLs), a 7.6 cm radius 12-post double-post-hole
convolute which connects the four outer MITLs in parallel, and a 5 cm
long inner MITL which connects the output of the convolute to a z-pinch
load. The authors have demonstrated they can deliver a 100 ns rise-time
20 MA current pulse to the baseline z-pinch load. They can reproduce the
peak MITL current to within ±1.6%. Power-flow measurements
indicate the vacuum section performs as expected until peak current.
Afterward, measurements and simulation results diverge

    ABSTRACT: An important consideration for the success of the ZR project, refurbishing the Z accelerator at Sandia National Laboratories, is limiting current loss in the vacuum section, ideally to no worse than the 5 – 10% seen on Z. The primary source for this loss is electrons flowing into the post-hole convolute from the four magnetically insulated transmission lines (MITLs). The MITLs on ZR have larger gaps to reduce the electron flow to values comparable to Z when operating at ∼40% higher voltage and ∼30% higher current. Electron flow in the vacuum section is analyzed with electromagnetic, particle-in-cell simulations, using two complementary simulation setups. First, the exact MITL profiles are modeled with high-resolution 2-D simulations out to large radius (typically r = 60 cm), providing accurate values for the electron flow into the convolute. Second, the convolute is modeled in 3-D, but with MITLs extending out only to r ∼ 30 cm. The 3-D MITL geometry is modified to provide the same electron flow into the convolute as the 2-D simulations. The 3-D simulations have detailed diagnostics for current loss and surface deposition heating in the convolute.

    ABSTRACT: High-energy pulsed-power devices routinely use field strengths above those at which broad-area, cathode-initiated, HV vacuum-breakdown occur (>10<sup>7</sup> to 3×10<sup>7</sup> V/m). Examples include magnetically-insulated transmission lines and current convolutes, high-current-density electron and ion diodes, high-power microwave devices and cavities and other structures for electrostatic and RF accelerators. Energy deposited in anode surfaces may exceed anode plasma thermal-desorption creation thresholds on the time scale of the pulse. Stimulated desorption by electron or photon bombardment also can lead to plasma formation on electrode or insulator surfaces. Device performance is limited above these thresholds, particularly in pulse length and energy, by the formation and expansion of neutral and plasma layers formed primarily from electrode contaminants. In-situ conditioning techniques to modify and eliminate the contaminants through multiple HV pulses, low base pressures, RF discharge cleaning, heating, surface coatings and ion- and electron-beam surface treatment allow access to new regimes of performance through control of plasma formation and modification of the plasma properties. Experimental and theoretical progress from a variety of devices and small scale experiments with a variety of treatment methods are reviewed and recommendations given for future work

    ABSTRACT: The Z pulsed power driver [1] at Sandia National Laboratories is used to develop high energy density z-pinch x-ray sources for inertial confinement fusion research and radiation effects testing, and to drive megabar pressures in material samples for equation of state studies. The entire pulsed power system is in the process of being replaced, improving reliability and increasing the energy delivered to the load.
