TXI Experimental Methods

X-ray Pump & X-ray Probe

• Nonlinear X-ray Methods - Such as four wave mixing and transient grating methods that can be mapped from the visible spectrum into the X-ray regime.
• Stimulated X-ray Emission Spectroscopy - Such as stimulated Raman or stimulated resonance inelastic X-ray scattering.
• Fourier Transform Inelastic X-ray Scattering  - Used in studying phonon dynamics.
• X-ray Pump / X-ray Probe – With beams from two independent undulators, making it unique among FEL facilities.
• Coincidence Catalysis - Where a soft X-ray is used to observer spectral dynamics and a hard X-ray is utilized as a probe.

Coherent Scattering & Imaging

• Coherent/Forward Scattering – High-intensity single shot diffractive imaging such as single particle imaging techniques.
• Small Angle X-ray Scattering (SAXS) – Including time resolved SAXS and Fluctuation X-ray scattering mehtods.
• Wide Angle X-ray Scattering (WAXS) & Crystallography – The 2 to 5 keV range enables strong native SAD and MAD phasing of nano-crystals.

Tender X-ray Spectroscopy

• X-ray Absorption Spectroscopy (XAS) – Time resolved studies of transition edges of most elements.
• X-ray Emission Spectroscopy (XES) – Including time resolved studies.
