Cobra | Silicon Power Corporation


The COBRA high current generator, designed and built by APP for the Lab of Plasma Studies at Cornell University, is capable of delivering a 1 MA, 100 ns current pulse to a low impedance load. COBRA is part of the new Center for the Study of Pulsed-Power-Driven High Energy Density Plasma at Cornell University. The generator went online in the spring of 2004.

Applications for COBRA include improving the performance of wire-array z-pinches as x-ray sources, laboratory simulation of astrophysical phenomena, studies of radiation dominated plasmas, interaction of plasma jets with target plasmas, and the atomic physics of highly stripped high-Z elements. Isentropic compression experiments at the 100 kbar level will also be carried out.
