مقاله ISI به زبان انگلیسی به همراه ترجمه فارسی عنوان و چکیده انگلیسی: Influence of the hot filament on the electrical breakdown characteristics in the presence of Ar/N2 Abstract The influence of a hot filament on the electrical breakdown characteristics is studied for different ratios of argon and nitrogen gases for a wide range of pressure. The vacuum tube consists of two parallel plane stainless steels used as cathode and anode accompanied with a tungsten filament located behind the cathode. Paschen’s curves are obtained for different ratios of argon and nitrogen as a function of pressure for various electric currents of the hot filament. The first and second Townsend coefficients as well as the ionization efficiency and secondary ionization coefficient are obtained for different filament currents. In addition, the influences of
