Figure 1
Overview of the plane-grating monochromator (PGM) beamline at FLASH. Behind the monochromator the beam is guided either to the PG1 or PG2 beamline branch by a cylindrical switching mirror unit (SMU). At PG1 a plane mirror M6 lifts the dispersed beam up to the Kirkpatrick–Baez mirror unit which refocuses the beam onto the sample of the permanently installed Raman spectrometer endstation. Only the focus sizes in the vertical direction for both beamlines are indicated in the figure. |
