Neutron radiography represents a powerful non-destructive testing technique that is still very much in development. The book reveals the amazing diversity of scientific and industrial applications of this technique, the advancements of the state-of-art neutron facilities, the latest method developments, and the expected future of neutron imaging.

The Rotating Target Neutron Source (RTNS-I), a high-intensity source of 14-MeV neutrons at the Lawrence Livermore National Laboratory (LLNL), has been used for applications in activation analysis, inertial-confinement-fusion diagnostic development, and fission decay-heat studies. The fast-neutron flux from the RTNS-I is at least 50 times the maximum fluxes available from typical neutron generators, making these applications possible. Facilities and procedures necessary for gamma-ray spectroscopy of samples irradiated at the RTNS-I were developed.

In this paper two topics will be presented: (a) the integral measurements and calculations of gamma-ray and neutron emission spectra due to a source of 14 MeV neutrons from materials of interest to thermonuclear reactors and (b) an overview of the new multi-user accelerator facility being built at LLNL. Under (a), recent measurements of the gamma-ray and neutron leakage spectra from materials ranging from Be to 238U pulsed with 14 MeV neutrons are presented. The Monte Carlo calculational analysis using the codes TART and SANDYL with the ENDL and ENDF/B-V photon-neutron libraries is discussed. Under (b), details of the new multi-disciplinary laboratory centered around a 10 MV Van de Graaff with four ion sources and 19 experimental beam lines will be given. The experimental program to be carried out in this facility will be discussed. 19 refs., 4 figs., 2 tabs.

In laser fusion, such as with the NOVA under construction at the Lawrence Livermore National Laboratory, the D-T reaction is expected to be complete within 100 ps. It is important to measure the time-dependence of the neutron flux from the fusion target. We describe the design of a new neutron detector of 20 ps resolving time that can be used to study the history of fusion burn.
