Determination of the temperature and density of helium gas plasma in a ۲.۵ kJ plasma focus device

In this paper, the visible spectrum behavior of impurities in a plasma focus device with helium applied gas is studied. For this purpose, an optical spectrometer is used to determine the impurities and to examine the Balmer series of helium gas in the chamber. The basis of optical spectroscopy methods is based on the excitation of atoms and its relationship with the absorption or emission of electromagnetic radiation. Considering equilibrium plasma and using the radiation spectrum, the temperature and density of helium gas plasma have been obtained as ۰.۵ keV and ۱۰۲۱/cm۳.
