| 概要 |
The necessary Lyman alpha laser power needed to obtain a given SNR is calculated for the laser resonance scattering measurements of hydrogen atom densities in high temperature plasmas. The results sho...w that a laser power of more than kW is needed for the measurements in the center of the plasma with good SNR, whereas 200 W is sufficient at the periphery. For the latter measurement, an excimer laser pumped dye laser (wavelength tuned at 365 nm) and a third harmonic generator by a tripling-gas-cell is being constructed, and preliminary measurements present promising results. In order to establish the laser resonance scattering technique in the hydrogen Balmer transition, the measurements were done against a plasma in a low density DC discharge in hydrogen. The results were satisfactory, confirming the validity of the technique.続きを見る
