ABSTRACT:
A device and method for cooling the edge of a top plate which partially surrounds an evaporant pocket in an electron beam gun. The invention involves the passage of coolant through a channel in the top plate. The channel is substantially parallel to and close enough to the edge of the top plate so that re-evaporation of evaporant condensed on the edge of the top plate is substantially prevented.
