Observation of Ion Swarm Behaviors in gas mixtures of CF3I, SF6 with N2 using Pulsed Laser-Induced Plasma Method

In our present work, we investigated the electron swarm parameters in gas mixtures of CF3I, SF6 with N2 at atmospheric pressure using Pulsed Laser-Induced Plasma Method. This paper presents the insulation characteristic of gas mixture containing CF3I as an alternative to SF6 from the view point of ion swarm parameters. The average drift velocities of positive and negative ions were investigated in gas mixtures of CF3I, SF6 with N2 at atmospheric pressure. The mixing rate of CF3I with N2 X was fixed to 0.1, 1.0, and 10.0%. The irradiation point of the pulse YAG laser Z was changed as 1.0, 2.0, and 3.0 cm below the upper rogowski electrode. In this way, weakly-ionized plasma was generated between the quasi-uniform field gap in test gas, and the average drift velocities of positive and…
