Structural investigation of Ayurveda Lauha (Iron) Bhasma

Journal of Ayurveda and Integrative Medicine, 2023
In Ayurveda, ‘Lauha’ (Iron) Bhasma is primarily used to cure diseases related to iron deficiency in humans. It is produced from purified raw metallic iron using a combination of multi-step traditional preparation processes described in the Ayurveda ...

Longitudinal beam splitting and coalescing using an off-momentum drifting barrier bucket

Physical Review Accelerators and Beams, 2021
There has been much research on longitudinal bunch splitting and coalescing for accelerator performance improvements in rf synchrotrons. In this paper, we report a scheme with several induction cells that goes beyond the limitation in which the phase ...

Wiggler radiation at a low-emittance storage ring and its usage for X-ray absorption spectroscopy

Journal of Synchrotron Radiation, 2022
A wiggler is a high-power insertion device that was used in the past to produce a smooth wide-band X-ray spectrum. It is widely believed that on low-emittance synchrotrons this X-ray source loses its spatial and spectral homogeneity and therefore becomes

Macromolecular Serial Crystallography (Volume II)

Crystals, 2022
The successful adaptation of the serial macromolecular crystallography approach at most 3rd generation synchrotron facilities allows a fruitful synergy between synchrotrons and XFELs that have accelerated the access and impact of this approach to an even

High-intensity effects on longitudinal bunch merging in hadron synchrotrons

Physical Review Accelerators and Beams, 2023
Longitudinal rf manipulation schemes have been widely employed for achieving various beam experiments and applications in heavy ion or proton (hadron) synchrotrons. For high-intensity hadron beams, longitudinal space charge and cavity beam loading play a

Kilohertz serial crystallography with the JUNGFRAU detector at a fourth-generation synchrotron source

IUCrJ, 2023
Serial and time-resolved macromolecular crystallography are on the rise. However, beam time at X-ray free-electron lasers is limited and most third-generation synchrotron-based macromolecular crystallography beamlines do not offer the necessary ...

Status and perspective of protein crystallography at the first multi-bend achromat based synchrotron MAX IV

Journal of Synchrotron Radiation
The first multi-bend achromat based synchrotron MAX IV operates two protein crystallography beamlines, BioMAX and MicroMAX. BioMAX is designed as a versatile, stable, high-throughput beamline catering for most protein crystallography experiments ...

Short-Wavelength Free-Electron Lasers

IEEE Photonics Journal, 2010
This paper presents a short review of the development of and the motivation for short-wavelength free-electron lasers. The first observation of coherent X-ray production was reported from the Linac Coherent Light Source in April 2009.

X-ray Phase Contrast Imaging from Synchrotron to Conventional Sources: A Review of the Existing Techniques for Biological Applications

Applied Sciences, 2022
Since the seminal work of Roentgen, X-ray imaging mainly uses the same physical phenomenon: the absorption of light by matter. Thanks to third-generation synchrotrons that provide a high flux of quasi-coherent X-rays, we have seen in recent years new ...
