Ultra-fast processes such as electrons shuffling in superconductors could be investigated using a tool which is basically the combination between an ultra-fast laser pulses from the Linac Coherent Light Source with a monochromator, which selects wavelengths from a large range of energy.
The result is a tunable X-Ray laser that can be used for studying materials.
Unlike hard X-Rays which, having high energy, penetrate the material, soft X-Rays barely penetrate matter at all. This property makes them the best form of light to probe many common materials.
The new instrument uses ultra-fast laser pulses in order to investigate chemical action of molecules.
