In this study , cold atmospheric pressure plasma jet used in treatment application was studied using COMSOL Multiphysics with the Finite Element Method . The device operates with argon gas at atmospheric pressure and by an alternating current power supply . Effective plasma parameters for treatment such as electron density and electron temperature and electrical potential have been investigated . Plasma parameters that affect treatment were determined by establishing a virtual laboratory before the experiment . The electron density value is suitable for therapeutic applications and The plasma temperature is less than the amount that the tissue is damaged . The gas inside the jet is argon and the flow rate is 5 slm . the pressure of the dielectric barrier discharge type of plasma jet is kept 1 atmosphere . The frequency of the electrodes is kept constant at 25 kHz and their Maximum voltage at 9 kV .
