A dicorotron device having the low voltage energization range of a "flit" corotron while maintaining the advantageous operating characteristics of a non "flit" design. A flick dicoroton assembly has been described in U.S. Patent No. 4,057,723 wherein a dicorotron wire is positioned in contact with a shield electrode. Here, an activation electrode 1 is mounted close to a glass coated coronode wire 2 but not necessarily in contact with it. Both coronode wire 2 and activation electrode 1 are separated'from a shield electrode 3 which is biased to a positive potential. The coronode wire 2 is energized from an alternating current source 4 with a potential in the range of 1.5 to 2 kilovolts RMS.
