Atmospheric pressure plasmas jet is widely used in the medical and agricultural fields. With this plasma jet, various kinds of stimuli are electrical, chemical, temperature, and affect biological responses. However, to improve the cost and performance is still a challenge of a plasma source. Recently, an insulating oil bath containing electrodes is considered as a new method to prevent spark generation, in which plasma performance is promoted by increasing supplied voltage. I also checked the same effect with our two ring electrodes plasma source. Small spikes have disappeared with an insulating oil coverage. Based on these ideas, the insulating oil was used to controlling the temperature on the ground electrode, and the plasma jet length of needle electrode configuration.
