ABSTRACT
The concepts and initial development efforts for a spatially resolved ion temperature diagnostic are described. The diagnostic is intended for Inertial Confinement Fusion experiments at the National Ignition Facility and is an integration of neutron aperture imaging and ion temperature techniques. The neutron imaging technique is extended by recording tomographic projections of the radiation-to-light converter on a streak camera. The streak record is used to calculate images at multiple times during the arrival of the thermally broadened 14.1 MeV neutron flux. The resulting set of images is used to determine the spatially resolved ion temperature.

    It has been shown that cosmic neutron flux can generate upsets in DRAM's and other electronics. A model simulating cosmic neutron flux has been developed using a 30 MeV Electron Linac. The slowing down of the electron beam (bremsstrahlung) in the target ultimately produces photoneutrons. MCNP4C...
