X-ray Crystallography

X-ray Crystallography

The size of the unit cell and the arrangement of atoms in a crystal may be determined from measurements of the diffraction of X-rays by the crystal, termed X-ray crystallography.
Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...

Atomic Force Microscopy

Atomic Force Microscopy

Atomic force microscopy (AFM) is a type of scanning probe microscopy that can analyze topographic details of various specimens like ceramics, glass, polymers, and biological samples. AFM offers over 1000 times more resolution than the optical imaging system. Images generated from AFM are three-dimensional surface profiles, offering an advantage over the flat, two-dimensional images from other imaging techniques.
The AFM Probe
The probe is regarded as the heart of any AFM setup and comprises the...

$X-ray Diffraction of Biological Samples$ 01:10

X-ray Diffraction of Biological Samples

X-ray diffraction or XRD is an analytical tool that utilizes X-rays to study ordered structures such as crystalline organic and inorganic samples, polycrystalline materials, proteins, carbohydrates, and drugs.
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are scattered by the electron clouds around the sample atoms. The X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal crystal...

Area of Science:

Materials Science
Crystallography
Synchrotron Radiation

Background:

Time-resolved crystallographic studies are crucial for understanding dynamic material processes.
Existing methods may lack the temporal resolution needed for ultrafast phenomena.
Synchrotron light sources offer intense X-ray beams for structural analysis.

Purpose of the Study:

To design and implement a mechanical X-ray chopper for microsecond time-resolved crystallography.
To achieve precise control over X-ray pulse duration for transient state analysis.
To enable in situ studies of photoactivated materials.

Main Methods:

A mechanical chopper with two counter-rotating asymmetric absorbers was developed.
The chopper operates at frequencies up to 50 Hz, synchronized with the X-ray beam.
Adjustable relative phasing of the absorbers controls X-ray pulse duration.

Main Results:

The chopper system achieves microsecond time resolution.
It allows for the generation of tunable X-ray pulse durations.
The system is integrated into the DIAMOND synchrotron I19 beamline.

Conclusions:

The developed X-ray chopper facilitates high-resolution time-resolved crystallographic studies.
This technology enables the investigation of transient states in materials.
It opens new avenues for in situ experiments on photoactivated systems.
