Abstract
Abstract A target structure is disclosed having superior electrical properties and mechanical strength. The target comprises a layer of KC1 supported by a dielectric material which in turn is deposited on a fine nickel metal mesh which provides mechanical support for the target. This structure is particularly useful in the construction of secondary electron conduction (SEC) targets.
