Abstract
PURPOSE: To obtain high secondary electron emission rate, by forming the perforated insulation thin film layer on the conductive substrate and remarkably improving the secondary electron emission performance with gas ion radiation.
CONSTITUTION: The perforated insulation thin film layer 3 is formed on the substrae 2, and DC voltage Vc is applied between the collection electrode 4 to collect the secondary electrons produced and the emission electrode 1. With this constitution, the ion flows are accelerated with DC voltage Vc, the surface of the emission electrode 1 is collided, emitting secondary electrons from the surface, and they are clooected with the collection electrode 4. With this construction, since the surface of the perforated insulation thin film layer is almost at the same potential as the collection electrode, strong potential is produced in this thin film layer, and the secondary electrons produced from the deep part emit from the surface while repeating multiplication by collision at the inside along the potential gradient.
