A double post-hole vacuum convolute diode for z-pinch experiments on saturn

We have successfully tested a double post-hole vacuum convolute for driving z-pinch loads on Saturn (32 TW, 1.9 MV, 40 ns FWHM, and 0.11/spl Omega/). We use the lower four insulators to feed four, conical self-magnetically insulated disk feeds (MITLs). The disk MITLs are convoluted using six anode posts (and cathode holes) to a single disk MITL (L /spl tilde/ 10 nH). A peak current of 12.5 MA was delivered to a low inductance short circuit load and 10.5 MA was delivered to a gas puff z-pinch load. Electron losses in the vacuum feed have been acceptable.
