  • Patent number: 9018604
    Abstract: An arrangement for handling a liquid metal for cooling revolving components of a radiation source based on a radiation-emitting plasma has the handling arrangement for the liquid metal comprises a reservoir of liquid metal in a vessel, a tempering device for adjusting the temperature moderately above the melting point of the metal, a pump unit for moving the liquid metal in circulation. The handling unit containing the reservoir and the pump unit is provided for transporting the metal into a separated source module via a feed pipe and a return pipe for guiding highly heated metal back from the source module into the reservoir. The return pipe is formed as a straight pipe slightly inclined to the reservoir to guide the heated metal back by action of gravity in a substantially laminar flow.
