The COBRA Accelerator Pulsed-Power Driver for Cornell/Sandia ICF Research

Abstract

This paper introduces and describes the new Cornell Beam Research Accelerator, COBRA, the result of a three and one-half year collaboration. The flexible 4 to 5-MV, 100 to 250-kA, 46-ns pulse width accelerator is based on a four-cavity Inductive Voltage Adder (IVA) design. In addition to being a mix of new and existing components, COBRA is unique in the sense that each cavity is driven by a single pulse forming line, and the IV A output polarity may be reversed by rotating the cavities 180 about their vertical axis. Our tests with negative high voltage on the inner MITL stalk indicate that the vacuum power flow has established reasonable azimuthal symmetry within about 2 ns (or 0.6 m) after the cavity output gap. Preliminary results with the accelerator, single cavity, and MITL are presented along with the design details and circuit model predictions.
