The requirements of plasma temperature and particle energies are effectively the same for inertial confinement fusion, ICF, and magnetic containment fusion, MCF. The n/tau product must also be similar; however, in ICF we increase the density to achieve efficient fuel burn up. Reactor gain pellets are expected to require densities of up to 10/sup 4/ x liquid density of DT. This corresponds to n approximately 10/sup 26/ cm-/sup 3/. The dimensions of the compressed core are of the order of microns. Thus, the diagnostics problems in ICF is to measure plasmas at approximately 10/sup 8/ K, n approximately 10/sup 26/ cm-/sup 3/, on scale lengths of microns with time scales of picoseconds. In this paper we discuss the extensive diagnostics which we have developed to measure the performance of our laser irradiated targets.
