Pulsed Arc

Four parameters of the He(I) 447.1-nm line with a forbidden component were measured. A pulsed arc was used as a plasma source. Electron density in the range (1.9–5.9) 1021 m−3 was measured with a CO2 laser interferometer. On the basis of the comparisons of the obtained results with several theories and empirical formulae for plasma density determination, it is shown that this line could be used for simple but precise electron density measurement, with an error < 10%.
