Calibration of National Ignition Facility neutron detectors in the energy range E<14 MeV.

We examine various options for calibration of the National Ignition Facility neutron detectors in the energy range E<14 MeV. These options include: downscatter of D–T fusion neutrons using plastic targets; nuclear reactions at a Tandem Van de Graaf accelerator; and “white” neutrons from a pulsed spallation source. As an example of the pulsed spallation option, we present calibration data that was recently acquired with a single crystal chemical vapor deposition diamond detector at the Weapons Neutron Research Facility at Los Alamos National Laboratory.
