Laser start-up system for magnetic mirror fusion

Abstract

A CO(2) laser system has been developed at the Lawrence Livermore Laboratory to provide hot start-up plasmas for magnetic mirror fusion experiments. It can irradiate a frozen ammonia pellet with a laser power density in excess of 10(13) W/cm(2) in a 50-nsec pulse. The system uses commercially available lasers. Optical components were fabricated both by direct machining and by standard techniques. The technologies used are directly applicable to reactor-scale systems.

“…In addition, velocity space instabilities increased the escape of the plasma. However recently Sokoloff (2007) has re-examined such systems (studied earlier by Frank et al 1977), in particular magnetic mirrors used in next generation Tokamak magnetic fusion energy devices where the toroidal magnetic field is stronger on the inboard side than on the outboard side. The resulting effects are known as neoclassical.…”
