Abstract

The proposed National Ignition Facility (NIF) is a large (1.8 MJ on target at 0.35 μm) multi-beam laser facility that will be used for Inertial Confinement Fusion (ICF). ICF implosions at this facility will produce core plasma temperatures over 10 keV and densities over 100 g/cm3. Properties of these plasmas can be measured by a variety of optical, X-ray, and nuclear diagnostic techniques such as those used at existing facilities like the Nova laser at the Lawrence Li vermore National Laboratory (LLNL). Some of these currently used techniques will be directly applicable to NIF; others require significant development. Damage of components close to the target will be a much greater issue at NIF, necessitating the development of distant detector techniques. To penetrate the larger targets, X-ray-based core diagnostics will need to utilize substantially higher energies than are in routine use today. Penetrating nuclear particle-based diagnostics will be particularly well suited to these implosions, and the higher nuclear yields will allow new techniques to be developed. Some examples of diagnostics used for high-density implosion experiments at Nova and corresponding development of new techniques for NIF are discussed.
