Usage of Liquid Metals in the Positron Production System of Linear Collider

In this publication we collected descriptions of some installations with liquid metals which could be used for high-energy colliders, ILC particularly, for the purposes of targeting, collimation, cooling, collection of secondary particles etc. Some important components of the system with liquid metals, such as pumps, nozzles, windows, and the fluid dynamics in the Lithium lens are described also.
