In the setup a quartz tube was inserted between the cone and plane electrodes in the direction parallel to the electric field. It was shown that the appearance and property of the discharge were sensitive to the size and the position of the quartz tube. When the tube was placed on the grounded plane electrode, the discharge intensity was found to improve gradually with the increase in the diameter of the quartz tube. Furthermore, with an appropriate distance between the bottom edge of the quartz tube and the plane electrode, the discharge tended to exhibit better performance in generating homogeneous diffusive plasma.
