摘要: Abstract Emission spectroscopy measurements of Balmer-β and Balmer-γ line profiles are carried out to study their shapes intensities as a function discharge parameters such fill pressure (3–7 mbar) input power (200–400 W). A technique based on determining the relative neutral atomic hydrogen emission lines is used evaluate electron temperature, whereas density extracted from Stark broadening (FWHM) H β profile. It found that both intensity exhibit significant dependence in same manner. However, weak contrast γ line. Based optical reported here, plasma can be selected optimize temperature density.
