Plasma Temperature Determination of Hydrogen Containing High-Frequency Electrodeless Lamps by Intensity Distribution Measurements of Hydrogen Molecular Band
Figure 9
The temperature dependence on the applied current for the Ar and H2 containing HFEDL. Temperature values obtained using Fulcher- (2-2)Q band are compared with ones obtained from Doppler profile of argon emission line with wavelength 772.4 nm. Line 1 is temperature of Ar + H2 () plasma obtained from Fulcher- (2-2)Q band; Line 2 is temperature of pure Ar plasma obtained from the Doppler profile.
