High-Energy Electron Accelerators as Pulsed Neutron Sources

Abstract

IN the time-of-flight method of distinguishing between neutrons of different energies, various types of pulsed neutron sources have been used. So far, however, the use of pulsed sources of high-energy electrons for generating neutrons through the (γ, n) reaction has not been reported. Experiments reported in the following letter show that the X-rays from a 3- or 4-MeV. linear accelerator will produce useful intensities of neutrons from a beryllium target.
