Relations between light emission and electron density and temperature fluctuations in a helium plasma

Ma, Shuiliang; Howard, John; Thapar, Nandika


The relations between three atomic lines, He I 667.8 nm (3¹ D → 2¹ P), 706.5 nm (3³ S → 2³ P), and 728.1 nm (3¹ S → 2¹ P), and the underlying fluctuations in a helium plasma are investigated for the quantitative interpretation of optical observations in plasma fluctuationmeasurements. Frequency dependent fluctuation amplitude ratios and phase delays between the line emission fluctuation and the electron density and temperaturefluctuations are calculated based on a quasi-static...[Show more]
