Linear Transformer Drivers for Propulsion and Power

Completed Technology Project

Project Introduction

Explore a variant of the linear transformer driver (LTD) concept being developed by Sandia Laboratories and University of Michigan, with the following differences: (1) Use smaller capacitors, for smaller bricks; (2) Assemble into much smaller cavities; (3) Add layers to the stack, introducing the super-cavity and super-stack. The rationale for this approach is to maintain as much of the LTD at lower voltage levels as possible, to eliminate the need for submerging components in oil or other arc retarding media, and to reduce weight. Also allows spreading components out as much as packing efficiency allows, to dissipate thermal energy. Efforts in Year 1 was focused on demonstration of LTD cavity. Year 2 will focus on stack demonstration, including cavity optimization, simultaneous operation of multiple cavities, voltage addition, and testing in vacuum. More »
