Femtosecond x rays from laser-plasma accelerators [PDF]

, 2013
Relativistic interaction of short-pulse lasers with underdense plasmas has recently led to the emergence of a novel generation of femtosecond x-ray sources. Based on radiation from electrons accelerated in plasma, these sources have the common properties

Multi-Lane Mirror for Broadband Applications of the Betatron X-ray Source

Photonics, 2021
A new generation of small-scale ultrafast X-ray sources is rapidly emerging. Laser-driven betatron radiation represents an important class of such ultrafast X-ray sources. With the sources driving towards maturity, many important applications in material

On the Role of Reduced Air Density Along the Lightning Leader Path to Ground in Increasing X‐Ray Production Relative to Normal Atmospheric Conditions

Geophysical Research Letters, 2019
Mallick et al. (2012, https://doi.org/10.1029/2012JD017555) discovered that subsequent‐stroke leaders in natural negative lightning could be more prolific producers of hard X‐rays and gamma rays than the first‐stroke leader in the same flash.

Crystallization of the regulatory and effector domains of the key sporulation response regulator Spo0A [PDF]

, 1999
The key response-regulator gene of sporulation, spo0A, has been cloned from Bacillus stearothermophilus and the encoded protein purified. The DNA-binding and phospho-acceptor domains of Spo0A have been prepared by tryptic digestion of the intact protein ...

Development of non-destructive testing (NDT) technique for HIPed interface by Compton scattering X-ray spectroscopy

Nuclear Materials and Energy, 2022
High energy X-rays (115.56 keV) were used to measure the HIPed interface of F82H steel. The X-ray energy spectra of the samples were analyzed focusing on W and Ta fluorescence X-rays, Compton scattering and elastic scattering X-rays.

Highly Collimated Monochromatic X-rays Generated by Collision of High-Energy Electrons with Tightly Focused Linearly Polarized Laser Pulse

Crystals, 2023
This article delves into the generation and modulation process of X-rays as high-energy photon sources. Using the principles of classical electrodynamics, this study enables nonrelativistic short pulse lasers to collide with high-energy electrons while ...

On the X-rays of permutations

, 2005
The X-ray of a permutation is defined as the sequence of antidiagonal sums in the associated permutation matrix. X-rays of permutation are interesting in the context of Discrete Tomography since many types of integral matrices can be written as linear ...

Electron beam welder X-rays its own welds [PDF]

, 1967
Beam of an electron beam welder X rays its own welds, enabling rapid weld quality checks to be made without removing the work from the vacuum chamber. A tungsten target produces X rays when hit by the beam.
