The development of neutron imaging at Lawrence Livermore National Laboratory (LLNL) has lead to the development of various neutron generating devices. From rotating apertures, to pulse valve gas systems, to hard targets, all have worked by placing an interaction material in front of a deuteron beam to generate neutrons. The next generation of neutron generating devices will utilize a precision rotating gas valve system that will place a deuterium gas pulse in front of deuteron beam at a rate of 120Hz. As with the other neutron generating devices, it will be part of a larger system that will include a linear accelerator that creates the deuteron beam, a scintillator detector and high resolution CCD cameras.
