Background compensation can be accomplished by simple subtraction of a background signal in the linear count rate meter. However, in the logarithmic count rate meter circuit (Cooke-Yarborough type), compensation must be accomplished by subtraction from each section of the logarithmic circuit before summing the outputs of the sections. The method is described and mathematically justified in the fol... View full abstract»

A mathematical model has been developed for estimating the performance of an Anti-Compton gama ray spectrometer. This spectrometer consists of a small cylindrical crystal surrounded by a larger, hollow cylindrical crystal, both composed of NaI(Tl). The results of a two-parameter study-incident gamma ray energy and relative crystal positions-are given. View full abstract»

The design of a 30-inch radius combined velocity and direction focusing mass analyzer is described. Application of this instrument as a high purity isotopic separator for research in nuclear physics, metallurgy, and semiconductors is also discussed. Brief mention is made of the development of p-n junctions for the detection of singly-charged ions of low kinetic energy. View full abstract»
