THE ELECTRONIC LOGIC OF A RANGE TELESCOPE FOR THE MEASUREMENT OF THE ISOTOPIC ABUNDANCE OF ENERGETIC PARTICLES IN SPACE.
Abstract
This report describes the electronic logic of a range telescope particle identifier. It discusses the logic and the nanosecond circuitry used to achieve a background rejection ratio of 10000 to 1, as well as the methods by which complicated data are cast into a form suitable for transmission over low information rate telemetry links. Solid-state detectors and amplifiers are discussed with particular regard to methods of obtaining the smallest possible resolving time. Finally, an assumed radiation environment similar to the worst anticipated in the radiation belts is used to predict the instrument's signal to noise ratio. Circuit diagrams of the amplifiers, limiter-discriminators, coincidence circuits, linear gates and the digital pulse height analyzer are given. (Author)
