MILLIMETER AND NANOSECOND RESOLUTION OF FAST NEUTRONS FROM AN INTENSE PLASMA DISCHARGE.

Abstract

Polyethylene collimators have been used with fast photomultipliers to spatially resolve the source of 2.45 MeV neutrons in a pulsed, dense, high-temperature, deuterium plasma. The axial distribution of the neutron source was measured with a spatial resolution of 2 mm and a time resolution of 3 nsec. A time-of-flight technique was developed to measure the average neutron velocity with just one photomultiplier and two widely separated plastic scintillators. (Author)
