Abstract
The multi-micro hollow cathode light source has a cathode plate, an insulation plate, an anode plate, and metal pieces. The insulation plate is sandwiched by the cathode plate and the anode plate. The cathode plate is made of copper. The centers of the cathode plate, insulation plate, and anode plate, are provided with holes, respectively. The holes form a penetrating though-hole. Linear slots are disposed in the cathode plate continuously extending from the hole in a cross shape. Each slot penetrates the cathode plate. Four metal pieces made of materials different from one another are inserted and buried in the four slots.
