The breakdown time delay and jitter are very important for the plasma-electrode Pockels cells(PEPC) electro-optic switch driven by one-pulse process. Their reduction is the key to improve the performance large aperture electro-optic switches. A method is proposed in this paper: the cathode is illuminated by ultraviolet ray, so that the secondary electron can be excited and come into a steady initialized electron flow on the surface of the cathode. Under the high voltage pulse, the initial electron flow avalanches quickly in the cell, and the helium gas breaks down and discharge happened. Experimental results have demonstrated that the method did reduce the switching time and the time jitter. And the average time jitter and the average breakdown time delay were cut down by 88% and 36%, resp
