Experimental Station 10-1

Beam line 10-1 is a wiggler side-station beam line for soft x-ray core-level spectroscopy. The endstation is equipped with a hemispherical photoelectron analyzer (SES-100), and detectors for Total Fluorescence Yield (TFY; Diode), Total Electron Yield (TEY; Channeltron) and Partial Electron Yield (PEY). It has a generic chamber that is compatible with both ex-situ and in-situ characterization of a large number of samples simultaneously. XAS can be recorded in AEY, TEY, FY yields. BL10-1 also houses a newly commissioned Transition Edge Sensor (TES) array for x-ray emission spectroscopy with ultrasensitive (large solid angle, 1 eV resolution) detection throughout the soft x-ray regime. This spectrometer is available for the user program in the partial fluorescent yield mode. Other modes such as RIXS or TES detection in combination with more complex sample environments or data acquisition modes are under development and will be available for the user program in the near future (please contact Dennis Nordlund or Sang-Jun Lee for more infomation).. Heating (up to 800C) and cooling (down to 50K, 80K LN2 typical) is available. In-situ capabilities are under development.
