The disclosed methods and apparatus improve the fabrication of solid fibers and microstructures. In many embodiments, the fabrication is from gaseous, solid, semi-solid, liquid, critical, and supercritical mixtures using one or more low molar mass precursor(s), in combination with one or more high molar mass precursor(s). The methods and systems generally employ the thermal diffusion/Soret effect to concentrate the low molar mass precursor at a reaction zone, where the presence of the high molar mass precursor contributes to this concentration, and may also contribute to the reaction and insulate the reaction zone, thereby achieving higher fiber growth rates and/or reduced energy/heat expenditures together with reduced homogeneous nucleation. In some embodiments, the invention also relates to the permanent or semi-permanent recording and/or reading of information on or within fabricated fibers and microstructures. In some embodiments, the invention also relates to the fabrication of certain functionally-shaped fibers and microstructures. In some embodiments, the invention may also utilize laser beam profiling to enhance fiber and microstructure fabrication.

Abstract
The present disclosure generally relates to an improved penetrator design and associated arming generator relocator adaptor. In some embodiments, the arming generator relocator adaptor is positioned external to the penetrator, thereby removing the need to mount the FZU inside the warhead or include traditional internal plumbing. The arming generator relocator adaptor allows the FZU to be rotated to an optimal position to arm the penetrator. While the improved penetrator design and arming generator relocator adaptor can be used independently of each other, in the preferred embodiment, they are utilized together.
