Abstract
The project described in this paper was undertaken during the 1956-57 academic year at the U. S. Naval Postgraduate School, Monterey, California. The purpose of this project was to redesign and make operational a thin magnetic lens Beta-ray spectrometer which could be used to determine the beta particle spectrum emitted by radioisotopes. Since to date, data concerning the theory, operation, construction, calibration and uses of this type spectrometer is scattered throughout the scientific literature, an attempt is also made to assemble selected essential concepts under one cover. It is hoped future research workers will find useful this information and equipment when adequate radioactive sources are made available through use of the AGN-201 nuclear reactor soon to be in operation in the U. S. Naval Postgraduate Engineering School. The equipment consists of the spectrometer with accessory detectors and vacuum system, two 220 volt DC motor generator sets and electronic control systems to regulate current to the spectrometer magnet coils. The writers wish to express their appreciation to Professor Edmund Milne for his advice and guidance; to Mr. M. K. Andrews, Chief Opticalman R. C. Moeller, U. S. Navy, and Mr. K. Smith for their willing cooperation and skillful assistance when aiding in construction and assembly of this equipment.
