PROPOSED ELECTRONIC SYSTEMS FOR THE LES RADIATION EXPERIMENT (SEPTEMBER 1964)
Abstract
To study the electron radiation environment of the Lincoln Experimental Satellite (LES), an electron detecting telescope has been proposed by C. Mack, et at. This report presents the proposed electronic system for this radiation experiment. This system is the result of a summer study by the author. The logical design on the electronic system is based on the use of a 'hybrid counter' as the scaler. The 'hybrid counter' employs the best features of both the 'fixed time' and the 'fixed count' scalers and can operate over a wide range of counting rates. Coincidence logic is programmed within the experiment so that the telescope can monitor the electron flux for energies from 60 Kev to 10 mev with counting rates from 100,000 counts/sec down to 0.1 count/ sec. The design of a charge sensitive solid state preamplifier and measurement chain is detailed. The integrating and differentiating time constant is set at 0.5 micro sec, and a noise linewidth of 27 Kev (fwhm) is achieved at 30C with a simulated input capacitance of 100pf.
