ABSTRACT:
A circulating coolant reservoir is used to uniformly cool a removable crucible in an electron beam gun assembly for vaporizing material to be deposited at another location. The outer surface of the crucible is substantially immersed in the coolant reservoir and coolant is circulated around the outer surface from diametrically opposed inlet and outlet lines whose axes are tangent to the reservoir walls and with an upwardly spiraling groove in the crucible outer surface.
