| Outline of Final Research Achievements |
By using a 2-stage light gus-gun, a polycarbonate bullet impacts onto a metal target in nitrogen gas and a hot gas plume is generated. Using a 12-ch Langmuir probe array, the plasma parameters are measured in the plume, by which the electron temperature of about 10000 C and the plasma density of about 10 to the power of 14 per cubic meter are obtained. During the cooling process of the plume, a lot of carbon nano-particles are synthesized and jetted out from the reaction chamber with a speed of about 2 km/s. The produced carbon soot is measured by the liquid chromatograph method, and 12 kinds of amino acids are detected. By the chiral isomer analysis, excess amount of L-type amino acid is detected. Reason of this deviation is now under investigation. By a model reaction analysis, we could make the reaction roots from CN radicals to amino acids in the hot gas plume.
