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...

$Interference and Diffraction$ 02:18

Interference and Diffraction

Interference is a characteristic phenomenon exhibited by waves. When two electromagnetic waves interact with their peaks and troughs coinciding, a resulting wave with enhanced amplitude is produced. This is known as constructive interference. In this case, the two waves interacting are in phase with each other.

Determination of Crystal Structures

Determination of Crystal Structures

In the late 1800s, the revelation that light extended beyond visible wavelengths led to the discovery of X-rays by Wilhelm Roentgen. Recognized as high-energy electromagnetic radiation with short wavelengths, X-rays prompted exploration into their interaction with crystals. Max von Laue proposed in 1912 that the periodic arrangement of atoms, ions, or molecules in crystals would cause them to diffract X-rays, a hypothesis confirmed through experiments with copper sulfate and zinc sulfide...

$X-ray Diffraction of Biological Samples$ 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...

X-ray Imaging

X-ray Imaging

German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with X-rays, and by 1900, X-ray was widely...

Background:

Grazing incidence mirrors are crucial for high-throughput X-ray telescopes.
Diffraction effects are typically negligible in X-ray optics due to short wavelengths.
Large obscuration ratios in grazing incidence systems can cause significant image degradation.

Purpose of the Study:

To investigate the impact of diffraction on X-ray telescope imaging.
To assess if diffraction effects can dominate other error sources.
To compare performance predictions with X-ray astronomy goals.

Main Methods:

Analysis of diffraction effects in tightly nested grazing incidence mirrors.
Parametric performance predictions for X-ray optical systems.
Comparison of predicted performance with established X-ray astronomy goals.

Main Results:

Diffraction effects can profoundly degrade image quality in grazing incidence X-ray telescopes.
These effects become dominant at the low-energy (long-wavelength) end of the spectrum.
Diffraction can be a more significant error source than others for certain X-ray telescopes.

Conclusions:

Diffraction must be considered in the design of high-resolution X-ray telescopes.
Minimizing diffraction effects is critical for achieving desired imaging performance.
Future X-ray telescope designs need to account for these optical phenomena.
