Low pressure glow discharge plasma diagnostics

In this thesis, the breakdown voltage, plasma potential for air and argon glow dischargesand light emission spectroscopy for argon discharge are investigated. A DC high voltagesupply was designed to do the experiments. By conducting experiments, firstly, Paschenvoltages measurements for air and argon are shown. Secondly, by using the double probesthe plasma potential measurements for air and argon are performed. There is a goodagreement with the literature results. Finally, the emission spectrum of the argon plasma,taken by Baki spectrometer, is examined. Using the locations of the peaks, the ionsgenerated in the argon discharge are found.
