Serial femtosecond crystallography diffraction

How do you measure the diffraction pattern of a crystal?
XRD finds the geometry or shape of a molecule using X-rays.
XRD techniques are based on the elastic scattering of X-rays from structures that have long range order.
The X-rays get diffracted by a crystal because the wavelength of X-rays is similar to the inter-atomic spacing in the crystals..
How does single crystal XRD work?
The key difference between X-ray crystallography and X-ray diffraction is that x-ray crystallography refers to the technique in which single crystals are exposed to x-rays, whereas x-ray diffraction refers to the technique in which a wide range of forms of the material are used for the measurement..
How does XRD determine crystal structure?

The X-rays get diffracted by a crystal because the wavelength of X-rays is similar to the inter-atomic spacing in the crystals..
What is the basis of the crystallographic diffraction techniques?
For single-crystal XRD, a crystal is mounted and centered within the X-ray beam.
For powder XRD, a polycrystalline sample is ground into a fine powder and mounted on a plate.
The sample (single- or polycrystalline) is irradiated with X-rays and the diffracted X-rays hit a detector..
What is the difference between single-crystal and XRD?
Powder X-ray diffraction reveals the crystal structure of the sample, while single-crystal X-ray diffraction additionally reveals the chemical content and locations of atoms..
Applications.
Single-crystal X-ray diffraction is most commonly used for precise determination of a unit cell, including cell dimensions and positions of atoms within the lattice.
Bond-lengths and angles are directly related to the atomic positions.
The resolution of spots collected on the detector increases as the diffracted angle increases.
Hence, the highest resolution will be at the edge of the detector, and if one determines the diffracted angle required, the distance of the detector from the crystal can be adjusted accordingly.

Each crystal is hit by a single X-ray pulse, forming a single diffraction pattern before being vaporized as a nano-plasma burst. The diffraction patterns are read out by a set of detectors, such as the two sets shown in Figure 1.

Serial femtosecond crystallography (SFX) is a form of X-ray crystallography developed for use at X-ray free-electron lasers (XFELs). Single pulses at free-electron lasers are bright enough to generate resolvable Bragg diffraction from sub-micron crystals.

What is Serial femtosecond crystallography (SFX)?

Serial femtosecond crystallography (SFX) usually involves a liquid jet of many (approximately 10 8) small crystals injected into the interaction point of an X-ray free-electron laser (XFEL)
