Proton Recoil Fast‐Neutron Spectrometer. Part I. Principles

摘要

A general equation for calculating the neutron energy spectrum from proton recoil counting data is derived. This equation is optimized subject to a constant total error to determine the most favorable experimental conditions. Feasible accuracy is illustrated by presenting a family of curves of the counting time (required for one point of a spectrum) plotted against total error with source intensity as a parameter. The calculations apply only to a ``good geometry'' experiment with a point source.
