Fabrication and characterization of cryogenic targets for inertial confinement fusion

PDF Version Also Available for Download.

Description

A new technique has been developed which is capable of fabricating uniform cryogenic targets for use in inertial confinement fusion. The essence of the technique is to directly wet a target with a cold helium gas jet, which results in freezing of the DT mixture contained in the target. A controlled amount of current is pulsed through a heater wire surrounding the target, giving rise to fast evaporation and refreezing of the DT-condensate into a uniform layer. Experiments, which have been performed with D/sub 2/-filled glass microshells, successfully produce uniform layers of both liquid and solid D/sub 2/ inside the ... continued below

A set of data illustrating the technique is presented and analyzed.
