Abstract :
The relationship between micropoints and field emission by a microchannel plate with a luminescent anode is studied. It is shown that the field emission electrons are emitted from the micropoints on the cathode surface. Most of micropoints disappear after emitting an electron, so they cannot keep emitting. The location of micropoints differs with the applied voltage, and they are distributed over the entire surface as the voltage is raised
