The book talks about the method of reacting using high-electronegative gases such as oxygen and adding them with the Macintor technology in order to make thin films with plasma atomization for the purpose of making gas sensing application.In this project, reactive magnetron plasma technique has been employed with different operating conditions for the electric discharges of the argon and argon / oxygen gases mixtures at various mixing percentage to achieve the optimum conditions for the plasma parameters generated to prepare thin films of Vanadium pentoxide with the high-quality nanostructure and specific electrical conductivity used in the construction and study the laboratory prototype characteristics of a gas sensor for both nitrogen oxides and ammonia.The DC electrical discharge properties in gases of argon and the mixture of argon /oxygen gases were studied, including the current-voltage, current-pressure and Paschen curve. The electrical plasma discharges properties were studied in different operating conditions (inter- electrodes spacing , gas pressure, discharge voltages). We found the optimum inter- electrodes spacing is (5cm).
