Stanford Synchrotron Radiation Lightsource

BL13-2 is an elliptically polarizing undulator (EPU) beamline dedicated for high energy resolution soft x-ray core-level spectroscopy. Its endstation features a versatile chamber capable of characterizing numerous samples simultaneously. It is equipped with detectors for XAS in the Total Electron Yield (TEY), Partial Electron Yield (PEY), Total Fluorescence Yield (TFY), and Partial Fluorescence Yield (PFY) modes. BL13-2 is also equipped with a Transition Edge Sensor (TES) spectrometer for x-ray emission spectroscopy (XES) and resonant inelastic x-ray scattering (RIXS), offering ultra-sensitive detection with a large solid angle and 1.5 eV resolution throughout the soft x-ray range. Heating (up to 110 C) and cooling (down to 50 K with LHe, typically to 80 K with LN2) capabilities are available. In-situ capabilities are currently under development.
