Abstract

Abstract

Features of a practical asymmetric electrode system were studied. The anode of this system is an analytical electrode such as Chang electrode and Ernst electrode, and the cathode is a simple electrode with line-arc structure. The electric field of the system was calculated with high-precision finite element method(FEM), and was analysed and compared with that of two symmetric electrode systems. With the analysis of effects of the parameters used in construction of the asymmetric electrodes, some suggestions were made for optimal choice of the shape of simple electrodes. The results show that the asymmetric electrodes are suitable for TEA CO2 lasers, and uniform electric field with required size can be obtained by proper choices of electrode parameters.
