A Composite Aluminum Conductor for Pulsed Power Applications at Cryogenic Temperatures and Method of Its Manufacture.
Abstract
The conductor contains high-purity aluminum embedded in an aluminum-iron-cerium alloy matrix. It is not superconducting but still has extremely low electrical resistance at service temperatures. Selection of the aluminum-base alloy matrix with diffusionless alloying elements (iron and cerium) allows production of a multifilamentary conductor with the aluminum filaments maintaining their original high purity and consequently their very low electrical resistivity, even after a high temperature annealing cycle is applied. The composite conductor has good properties for both electromagnetic and thermal diffusion, which are critical to high power, fast-pulse operation. (Author)
