Liquid targets and the liquid system. (a) A gravity-driven water film. The thickness is 210 μm. (b) A pump-driven water line with a diameter of 260 μm, which is guided by a syringe needle. (c) A home-built liquid system, which needs only 50 ml water for several hours running. A syringe is used as a jet for producing a liquid line.
