Xfel crystallography

How does an XFEL work?
How do they work? At SLAC's XFEL the Linac Coherent Light Source (LCLS), a drive laser generates a pulse of ultraviolet light, which travels to an injector "gun" and strikes the surface of a copper plate.
The plate releases a burst of electrons, which are accelerated by a series of devices to boost their energy..
How does the Xfel work?
XFELs are like a cross between an X-ray microscope and a laser.
They work by producing very intense pulses of light at an astonishingly fast rate – we're talking between hundreds and tens of thousands of light pulses each second..
What are the advantages of Xfel?
XFEL offers the advantages of both X-rays and lasers, with peak brightness 9 orders of magnitude higher, pulse width 3 orders of magnitude shorter, and coherence more than 3 orders of magnitude higher than typical third-generation synchrotron radiation sources..
What is the principle of Xfel?
XFELs).
The longitudinal distribution of electrons in the bunch is “cut” into equidistant slices with a separation corresponding to the wavelength λph of the emitted radiation which causes the modulation..
What is the use of Xfel?
Hence, XFELs use long undulator sections that are tens or hundreds of meters long.
This allows XFELs to produce the brightest X-ray pulses of any human-made x-ray source.
The intense pulses from the X-ray laser lies in the principle of self-amplified spontaneous emission (SASE), which leads to microbunching..

Since the total intensity per pulse is about 1012 photons and there are about 1000 spikes per pulse there are now about 109 photons in the coherence volume.
This is illustrated in Fig. 9 where we have assumed the natural 0.2% bandwidth of the XFEL beam.
We can now begin to do multiphoton experiments.

Can XFELs improve photocrystallography and femtobiology?

The femtosecond pulse length afforded by XFELs has extended the time resolution of photocrystallography by at least three orders of magnitude from ~100 ps limited by the electron bunch length at synchrotron sources

As a result, femtochemistry and femtobiology studies are now accessible with X-ray analysis

What is XFEL protein crystallography?

These advancements make it possible to measure the anomalous diffraction signals for experimental phasing purposes [ 11] and the dynamic nature of protein at room temperature

One major application of XFEL protein crystallography is the structure determination of membrane proteins, which are naturally good targets for drug development

What is XFEL Serial femtosecond crystallography (SFX)?

The atomic resolution structures of several important G-protein coupled receptor (GPCR) proteins have been resolved using the XFEL serial femtosecond crystallography (SFX) method [ 12, 13 ]
