Abstract
Characteristic of prebreakdown emission current has been studied. It is known that the electrons are emitted from minute projections on the cathode surface where the field strength is more than 10 [V/cm]. We observed the location of emission sites by using a micro-channel-plate with a luminescent screen, and discussed the effects of the heat treatment on the behavior of emission sites. As a result, the heat treatment decreases not only the number of emission sites but also the number of electrons emitted from one projection. And the annealing effect becomes conspicuously with increasing the temperature of annealing
