been adopted for these shots offering some degree of uniformity among samples since each sample reported has The Nevada Shocker powered by nine 0.28 [tF been fired only once. Such a sample is considered virgin. capacitors in a Marx Bank configuration yielding a Over sixty virgin, polished, Rexolite (C-Lec Plastics Inc.) maximum standup voltage and energy of 540 kV and 4.54 plastic samples have been examined. Only the most kJ respectively drives a 14.2 nF (in charging mode) typical signatures are presented. Blumlein. The Blumlein with self-breaking water switch This paper is organized as follows. Section II provides Blulei. helumei wih slfbrekin wterswich information on the Nevada Shocker. The polishing generates a 46 ns (theory) to 50 ns (experimental) pulse guided by a 7 Q discharge transmission line to a parallel procedure is explained in Section III. Section IV and V 106 Torr vacuum environment. Four respectively provide shot signature data for the open and short-circuited diode and for shots performed on polished novel UNLV dots equally spaced on a 1.25" radius circle .o.t.s embedded about 1 mm below the anode electrode surface interrogates the power flow between the diode plates. II T The novel dot allows for both H and D fields at the . HE NEVADA SHOCKER surface of the electrode to be measured at a single point. Preliminary discussions of breakdown will be presented The Nevada Shocker is a pulsed power source at the based on a number of open and short-circuited shots and a University of Nevada Las Vegas employing Marx bank number of single shot 1" and 2" long, 1" diameter and Blumlein technologies. For flashover studies, each of Rexolite samples between the electrodes. A null shot will the of the nine 0.28 [tF Marx bank capacitors is charged to also be presented for comparison. 50kV (capacitance upon erection CMB=3 1. lnF). The energy is release through a loosely wound Marx bank coil
