Article Synopsis
- BESSY II has successfully implemented resonant inelastic X-ray scattering in the XUV-regime, achieving a bandwidth of a few meV at various X-ray edges, including transition metals and light elements like carbon.
- A new low-energy beamline, UE112-PGM1, has been specifically designed to focus the beam to 1 µm vertically and 20 µm horizontally, facilitating high-resolution spectroscopy.
- The beamline demonstrates a resolving power better than 10,000 at 64 eV, while the associated high-resolution spectrometer shows a resolving power range of 3000 to 6000.

A new but yet well proven way of making elliptically polarized dipole radiation from the BESSY II storage ring applicable to the SX700-type collimated plane-grating monochromator PM3 is described. It is shown that due to the limited vertical acceptance of the grating a simple use of vertical apertures is not possible in this case. Rather, deflecting the beam upwards or downwards by rotating the vertically collimating toroidal mirror M1 around the light axis leads to excellent performance.
