Description: Electron diffraction patterns for single crystal and polycrystalline materials are displayed on a CRT screen. A Welch model 2639 'Electron Diffraction tube' is used in an experiment in ...

The first pulse — the pump — creates excited states ... From the intensities of the zero- (m = 0) and first-order (m = ±1) diffraction, the amplitude and phase of the harmonics from the ...

Figure 2: Protein molecules, virus particles, nanocrystals and cells can be delivered in vacuum to a high-intensity X-ray FEL pulse, in droplets of water or other liquids. Figure 3: Diffraction ...

What is the Diffraction Limit? The diffraction limit is a fundamental barrier in optical microscopy that sets the minimum size of features that can be resolved using conventional light microscopes. It ...

"By fine-tuning X-ray pulse conditions, we will be able to observe ... Non-linear enhancement of ultrafast X-ray diffraction through transient resonances, Nature Communications (2025).

The waves always 'spread' to some extent into the area beyond the gap. This is diffraction - the spreading out of waves when they go through a gap, or past the edge of a barrier. The extent of the ...

When a laser beam is incident on a narrow opaque object such as a fine wire or a strand of hair, the resulting diffraction pattern is similar to the diffraction pattern of a slit of the same width as ...

The study, led by Sophie Parsons, a UCSD graduate student participating in LLNL's Academic Cooperation Program, utilized ...

Definition: X-Ray Diffraction (XRD) is a powerful analytical technique used to characterize the atomic and molecular structure of a crystal. By measuring the angles and intensities of diffracted beams ...
