Tandem mirror and field-reversed mirror experiments

Description: This paper is largely devoted to tandem mirror and field-reversed mirror experiments at the Lawrence Livermore Laboratory (LLL), and briefly summarizes results of experiments in which field-reversal has been achieved. In the tandem experiment, high-energy, high-density plasmas (nearly identical to 2XIIB plasmas) are located at each end of a solenoid where plasma ions are electrostatically confined by the high positive poentials arising in the end plug plasma. End plug ions are magnetically confined, and electrons are electrostatically confined by the overall positive potential of the system. The field-reversed mirror reactor consists of several small field-reversed mirror plasmas linked together for economic reasons. In the LLL Beta II experiment, generation of a field-reversed plasma ring will be investigated using a high-energy plasma gun with a transverse radial magnetic field. This plasma will be further heated and sustained by injection of intense, high-energy neutral beams.

300-kJ, 200-kA Marx module for Antares

Description: Antares is a 100-kJ CO/sub 2/ laser driver for inertial confinement fusion experiments. The power amplification stage is pumped by an electron-beam-controlled gas discharge. There are 24 annular discharge regions, each requiring energy input of 250 kJ at 550 kV, in a 2-used pulse. The energy storage module chosen for this system is a single-mesh pulse-forming network. To provide sufficient energy margin each module stores 300 kJ. A prototype 300-kJ Marx has been built and tested at the Los Alamos Scientific Laboratory. This has been used as a test bed for components, triggering, and instrumentation.
