Figure 9
Schematic lateral cut through the beamline in front of the REMI. The FEL beam enters from the left. Shown are differential pumping tubes (orange), bellows (yellow), apertures (dark-green), valves (light-blue), slits (light-brown), screens (light-green) and a light baffle (blue). The XUV split-delay and focusing optics (cf. Section 3[link]) is also illustrated. The IR incoupling (red) is discussed in Section 6[link]. The inset (a) shows the dimensions of the differential pumping tubes (colored orange in the main figure). At the entrance and the exit, the tubes are configured with sharply chamfered copper apertures (orange). The length l varies between 185 and 287 mm depending on the position of the tube in the beamline. (b) Dimensions of the light baffle (colored blue in the main figure). At the entrance and the exit, two apertures made of roughened 625 µm thin silicon wafers (blue) are inserted. The figure is modified after Schmid (2018BB45).
