Article Synopsis
- There is a performance gap in monochromaticity and brilliance between conventional X-ray tubes and large-scale synchrotron sources, making synchrotrons impractical for smaller labs due to their size and cost.
- Laser-driven compact synchrotron light sources (CLS) offer a solution by combining an infrared laser with a small electron storage ring to produce high-quality monochromatic X-rays through inverse Compton scattering.
- A successful experiment demonstrated that CLS can achieve advanced X-ray multimodal tomography (including phase, dark-field, and attenuation-contrast) with impressive results, particularly in applications like CT scans of small animals, outperforming traditional methods.
Article Synopsis
- Structural genomics projects need X-ray diffraction and NMR spectroscopy for solving protein structures, and advanced facilities are often required for data collection.
- The paper introduces a new laboratory-scale synchrotron light source called the Compact Light Source, which can replicate many key synchrotron applications in X-ray science.
- Successful tests showcased its capability by determining the high-resolution structure of a protein from Mycobacterium tuberculosis using X-ray diffraction data from this new source.
Fully coherent x-ray pulses from a regenerative-amplifier free-electron laser.
Phys Rev Lett
April 2006
We propose and analyze a regenerative-amplifier free-electron laser (FEL) to produce fully coherent, hard x-ray pulses. The method makes use of narrow-bandwidth Bragg crystals to form an x-ray feedback loop around a relatively short undulator. Self-amplified spontaneous emission (SASE) from the leading electron bunch in a bunch train is spectrally filtered by the Bragg reflectors and is brought back to the beginning of the undulator to interact repeatedly with subsequent bunches in the bunch train.
