BL5-4 is a normal incidence monochromator beamline optimized for high-resolution angle-resolved photoemission spectroscopy (ARPES) in the photon energy range of 7 - 40 eV with polarization control (circular polarizations: 7 - 40 eV, linear polarizations: 16 - 40 eV). The dedicated experimental end station is equipped with a SCIENTA DFS30-8000 electron spectrometer. This system is capable of performing ARPES experiments with a total energy resolution of a few meV and an angular resolution of 0.3°.
BL5-2 is a plane grating monochromator beam line optimized for high-resolution, micro-focused angle-resolved photoemission spectroscopy (ARPES) in the photon energy range of 18 - 200 eV with full polarization control. The dedicated experimental end station is equipped with a SCIENTA DFS30 electron spectrometer. This system is capable of performing ARPES experiments with a total energy resolution of a few meV and an angular resolution of ~0.1°. It is also equipped with a low-temperature sample manipulator with three degrees of freedom of rotation, which can be cooled down to ~7 K.
Beam line 2-3 is a bending magnet side station dedicated to x-ray imaging and micro x-ray absorption spectroscopy (XANES, EXAFS) of biological, material science, and geological samples. A SIGRAY axially symmetric mirror system is used to achieve microfocus with a beam size of either ~ 5 x 5 microns or ~ 1 x 1 microns.
Beam line 2-2 is a bending magnet experimental station setup for general x-ray absorption spectroscopy in the 4.5 keV to 37 keV range. This beam line features a QEXAFS capable water cooled double-crystal monochromator. Si(111) or Si(220) crystal sets can be installed. White beam experiments are possible. On-the-fly scanning modes are available to shorten acquisition time and enable time resolved studies. In addition, this beam line is equipped with a comprehensive suite of hardware and software tools that support R&D in beam line automation.
Beamline 2-1 is used for structural studies across a range of materials systems focused on powder diffraction and reflectivity. In addition to high throughput, high resolution diffraction data the beamline can accommodate highly customized in-situ and operando configurations. The beamline is frequently used to study electrochemical reactions, material response to variable temperatures or gas environments, and other user-defined setups.
Beamline 1-5 is a materials science beamline that has been used for a host of science areas, for example polymer morphology during deconstruction, nanoparticle synthesis, catalyst support materials, and hydrated skin samples. Beamline 1-5 is a bend magnet end station focused on small-angle x-ray scattering (SAXS) measurements, but with the possibility of also doing wide-angle x-ray scattering (WAXS). It can also be configured for simultaneous SAXS/WAXS. BL1-5 is equipped with two area detectors: Dectris Pilatus 1M (SAXS) and Dectris Pilatus 100K (WAXS).
Beam line 4-3 is a wiggler side-station dedicated for x-ray absorption spectroscopy and EXAFS measurements on biological, environmental, catalysis, and materials systems. This station enables tender x-ray measurement (S K-edge and up, i.e. 2.4-5 keV) in addition to hard x-rays (up to 10 keV). Separate in-hutch experimental setups are required for the two different energy ranges. In the tender x-ray energy range, the station is setup with a He flight path from the beam line optics to the sample to avoid absorption by air.
