High efficiency electron beam gun foil support
Abstract
The reduction of the grazing angle of electron is an electron gun with a cathode emitting a beam of electrons which pass through a thin foil into a chamber is accomplished by geometrically tailored electron gun foil supports. One embodiment of the invention replaces the conventional rectangular shaped ribs with a set of triangular shaped ribs which produce a grazing angle. Another embodiment of the tailored foil supports entails the addition of triangular shaped caps to existing rectangular shaped ribs. The resultant reduction of the grazing angle of electrons improve the transmission efficiency of the electron gun and reduces the heat buildup on the supports and foil.
