This low energy beamline serves the permanent stations for angle-resolved photoelectron spectroscopy, 13 and 12 ARPES. It is designed to deliver a high flux of photons with very high energy resolution in the range from 5 to 250 eV. In addition to its normal operation with grazing incidence angles, the monochromator also offers a normal indcidence option to retain flux and polarization at the lowest energies.
The monochromated beam branches into two lines to serve the 12 (left) and 13 (right) setups. The latter has a focus of 250 µm.

Flux and bandwidth with various gratings
This experiment is built in a collaborative effort by the IFW Dresden, TU Dresden and the HZB, to enable experiments that require the highest energy resolution at ultimately low sample temperatures. To achieve this goal, all contributions to experimental broadening ---the resolution of both the excitation source and the electron energy analyzer as well as the sample temperature--- have been reduced to ≤1 meV or their equivalent, yielding the name of the station: 1 meV x 1 meV x 1 K = 13.
