Research Abstract

We developed an equipment for measuring Raman scattering in a low-frequency region using an iodine gas filter and a CCD monochromator. The intensity of scattering light of a laser beam was reduced to 1/1000 by the scattering light passing through the gas filter kept under a suitable temperature. However, the magnitude of reduction significantly changed with time. The reason would be the stability of temperature of the laser head. We also checked the resolution of the CCD monochromator using some emission lines from neon gas and confirmed that it has an enough resolution (1.7 cm-1) for measuring the Raman scattering. In addition, we successfully produced dust particles in an acetylene plasma by examining suitable conditions.
