Abstract:Atmospheric argon plasma jets are generated with the rod-tube/tube high voltage electrode and a ring ground electrode at 8 kHz sinusoidal excitation voltage. It is found that the vibrational temperature, electronic excitation temperature, atomic oxygen density and spectral intensity with the rod-tube high voltage electrode are enhanced significantly than that with the tube high voltage electrode. The atomic oxygen density, molecular nitrogen density, and average electronic density are about magnitude of 10(16) cm(-3), 10(15) cm(-3), and 10(12) cm(-3) respectively, and the excited Ar, N-2, OH and O are presented in the plasma plume with the rod-tube/tube high voltage electrode.
