Abstract: In this paper,the possible PS exposure source based on a novel N2 plasma generated in direct current hollow cathode discharge(HCD) is investigated.With the applied voltage 580 V,current 1.8 A and working pressure 70 Pa an optical power density of 0.46 mW/cm2 is obtained,in which the conventional PS plate can be well photosensitized.As a result the efficiency of photosensitivity this source is discussed in detail from the color density change and the FTIR analysis on the coating material.

Key words: hollow cathode discharge (HCD), PS plate, high frequency pulse plasma
