A method to operate an apparatus for feeding liquid metal to an evaporator device in a vacuum chamber, wherein the feed tube runs from a container adapted to contain a liquid metal to the evaporator device and wherein an electromagnetic pump is provided in the feed tube and a valve in the feed tube between the electromagnetic pump and the evaporator device. An at least partially gas permeable electromagnetic pump, which is enclosed in a pressure controlled enclosure, is used in the method wherein electromagnetic pump and the pressure controlled enclosure are controlled such that filling and draining of the evaporator device and feed tube can be done without affecting the vacuum pressure in the vacuum chamber.

Method to operate an apparatus for feeding liquid metal to an evaporator device

A method to control the temperature of an electromagnetic pump in an apparatus wherein a liquid metal is supplied through a feed tube from a container adapted to contain a liquid metal to an evaporator device in a vacuum chamber, wherein the temperature of the electromagnetic pump is controlled by controlling one or more of
