Paper Abstract

Laser fusion involves the compression using very high power laser beams of a pellet containing fusionable fuel, such as a deuterium-tritium mixture, to such high densities and temperatures that it ignites and yields a net energy gain. The deposited energy causes a plasma to ablate from the target surface which drives the implosion. The physics issues to achieve success are numerous; they include: the laser absorption and pellet surface acceleration processes must be benign and efficient; uniform megabar pressures must be gen-erated by the ablating plasma to accelerate the target shell inward with a velocity over 150 km/sec and with about 1% accuracy; throughout this implosion the fuel must remain cold. To study these physics issues a number of novel diagnostics gre required. They involve measurements of photon and particle energies from 1 eV to 10 5 eV with subnanosecond time-resolution and micron spatial resolution. Many of these diagnostic techniques and their applications in the NRL laser fusion experiment are described.
