The field emission gun (FEG) is a standard Schottky emitter with an electronic rack (extraction supply, gun lens) separate from the electronics of the ...
A field emission gun (FEG) is a type of electron gun in which a sharply pointed Müller-type emitter : 87–128 is held at several kilovolts negative potential ...
An electron gun that utilizes the field emission phenomenon. The field emission phenomenon means as follows: When a strong electric field is applied to the ...
Field emission guns utilize an extremely sharp metal tip made of single-crystal tungsten. An electric field is applied by an anode and the field is concentrated ...
