Soft X-ray Spectromicroscopy (SM) 10ID-1


The Spectromicroscopy (SM) beamline user group has strong research programs ranging from polymer science, environmental science, and biological applications to novel material design and magnetic imaging.

An Apple II type undulator provides an intense beam in the 130-2700 eV energy range with user-specified polarization (varying from an arbitrary inclined linear polarization to circular polarization). An infinity corrected plane grating monochromator (PGM) with vertical dispersion plane is designed for a nominal resolving power of 3000 and flux as high as possible. The PGM works with collimated light and allows for the free choice of grating magnification parameters, providing the best compromise between energy resolution (approaching a resolving power of 10000), high order rejection and grating efficiency.

  • Scanning Transmission X-ray Microscope (STXM) is an advanced microscope designed at the CLS, similar to a prototype which operated on Beamline at the Advanced Light Source (Berkeley)
  • Cryo-STXM (commissioning)
  • X-ray Photo emission Electron Microscope (X-PEEM) that has been acquired commercially from Elmitec
  • Photoemission Electron Microscope (PEEM) (same microscope using UV source)


Entrance slit-less plane grating monochromator; a single grating substrate with three stripes. Optics allows easy switching between the two parallel endstations, STXM and X-PEEM.
