Abstract:

At SSRL, we’ve been running two TES spectrometers for soft x-ray spectroscopy at BL 10-1 and 13-3. The TES spectrometer is an energy-dispersive detector made with an array of transition-edge sensor (TES) microcalorimeters. They are equipped with a wide
energy range of 200—1500 eV, an energy resolution of 1–2 eV FWHM, and a solid angle that is orders of magnitude greater than that of wavelength-dispersive spectrometers. This unique combination makes the TES an attractive option for advanced photon-in/photon-out measurements such as RIXS (resonant inelastic x-ray scattering), RSXS (resonant soft x-ray scattering), and PFY-XAS (partial fluorescence yield detected x-ray absorption spectroscopy) especially for very dilute samples. In this poster, we will present several science cases from BL 10-1 and 13-3 that were enabled by the synergy between the TES and each beamline’s capability. We will also describe our efforts to make the TES spectrometers a more powerful user instrument.
