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...

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...

NMR Spectrometers: Radiofrequency Pulses and Pulse Sequences

NMR Spectrometers: Radiofrequency Pulses and Pulse Sequences

A pulse is a short burst of radio waves distributed over a range of frequencies that simultaneously excites all the nuclei in the sample. Upon passing a radio frequency pulse along the x-axis, the nuclei absorb energy corresponding to their Larmor frequencies and achieve resonance. This shifts the net magnetization vector from the z-axis toward the transverse plane. This angle of rotation of the magnetization vector, or the flip angle, is proportional to the duration and intensity of the pulse.

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...

Background:

Chirped X-ray pulses are crucial for various scientific applications.
Laue-type pulse compressors (LPCs) are used for X-ray pulse compression.
Nonlinear dispersion in crystals and multilayers can affect compressor performance.

Purpose of the Study:

To theoretically investigate the impact of nonlinear dispersion on chirped X-ray pulse compression in LPCs.

Optimization of LPC configuration parameters.
Simulation of LPC performance using LCLS-II-HE parameters.

Main Results:

Optimal crystal thickness for LPCs is found to be half of the Pendellosung period.
This optimal thickness minimizes the impact of nonlinear dispersion on pulse compression.
Deviations from optimal thickness offer potential for generating ultra-short multi-color X-ray pulses.

Conclusions:

Nonlinear dispersion significantly impacts LPC performance, but can be mitigated through optimal design.
The study provides a method for optimizing LPCs for chirped X-ray pulse compression.
