Beamline 15-2 is a state-of-the-art undulator experimental station specializing in advanced hard x-ray spectroscopy. The end station features cutting-edge instrumentation, including a 7-crystal Johann spectrometer and an 8-crystal von Hamos instrument for sub-core hole lifetime resolution x-ray emission spectroscopy. It also houses high-throughput and high-energy-resolution x-ray Raman spectrometers with resolutions of 0.3 eV, optimized for both low-q (40-crystal) and high-q (30-crystal) scattering geometries.

Beamline 13-3, is dedicated to advancing research in quantum materials and diverse areas of materials science through resonant soft x-ray scattering (RSXS) and spectroscopy. Equipped with a spherical grating monochromator (SGM) and an elliptical polarizing undulator (EPU), the beamline provides full polarization control, including linear (vertical and horizontal) and circular (left and right) modes. Operating within a photon energy range of 250 eV to 1800 eV, it accesses key absorption edges such as the C, O, F, and Al K-edges, 3d transition metal L-edges, and 4f rare-earth M-edges.

Beam line 11-3 is a fixed energy (E = 12.7 keV, λ = 0.9763 Å) wiggler side station dedicated to wide-angle X-ray scattering techniques (WAXS). The beam line specializes in grazing-incidence geometry measurements, but transmission geometry measurements are also available upon request. The high flux of the instrument paired with a Rayonix MX225 CCD area detector enables rapid data acquisition across variable q-ranges for in-situ/operando X-ray scattering measurements.

Beam line currently closed for upgrade.

Beam line 8-2 can be used to probe a wide range of core levels using photoemission and x-ray absorption spectroscopies. It is equipped with a general-purpose end-station offering a high throughput setup for soft x-ray spectroscopy measurement. BL8-2 has been optimized for seamless sample positioning and the ability to measure across many different energies, consecutively, rendering it particularly useful for characterizing large numbers of samples with multiple elements such as energy storage materials or catalysts.

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.
