A high-temperature furnace for multimodal synchrotron-based X-ray microscopy and diffraction imaging

open access: yesJournal of Synchrotron Radiation
The design, calibration and initial application of a non-contact high-temperature furnace developed for in situ synchrotron X-ray experiments are presented. The system enables a stable operation up to 1000°C, with heating rates exceeding 6000°C min−1 and

Spin response function technique in spin-transparent synchrotrons

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
Small perturbative fields in a synchrotron influence both the spin and orbital motion of a stored beam. Their effect on the beam polarization consists of two contributions, a direct kick and an effect of the ring lattice due to orbit perturbation.

Crystal structure of a bacterial photoactivated adenylate cyclase determined by serial femtosecond and serial synchrotron crystallography

open access: yesIUCrJ
OaPAC is a recently discovered blue-light-using flavin adenosine dinucleotide (BLUF) photoactivated adenylate cyclase from the cyanobacterium Oscillatoria acuminata that uses adenosine triphosphate and translates the light signal into the production of ...

A novel approach using nonlinear surfaces for dynamic aperture optimization in MBA synchrotron light sources

open access: yesScientific Reports, 2023
MBA cell-based synchrotron light sources have enabled an unprecedented increase in beam coherence and brightness, greatly benefiting the scientific disciplines that rely on X-ray techniques. However, controlling the electron dynamics is a theoretical and

Giant Rashba effect at the topological surface of PrGe revealing antiferromagnetic spintronics

open access: yesScientific Reports, 2017
Rashba spin-orbit splitting in the magnetic materials opens up a new perspective in the field of spintronics. Here, we report a giant Rashba spin-orbit splitting on the PrGe [010] surface in the paramagnetic phase with Rashba coefficient α R  = 5 eVÅ. We

Coherent synchrobetatron resonance

open access: yesPhysical Review Special Topics. Accelerators and Beams, 2007
Coherent synchrobetatron resonances can present a serious limit for low-energy synchrotrons. An excitation of a dipole transverse mode is considered at resonance condition. As an example, the growth rate for the Fermilab Booster is estimated.

Generation of incoherent Cherenkov diffraction radiation in synchrotrons

open access: yesPhysical Review Accelerators and Beams, 2020
Incoherent Cherenkov diffraction radiation was recently produced in the Cornell electron storage ring using counterpropagating beams (electrons and positrons) passing in the close vicinity of a dielectric made of fused silica.

Serial millisecond crystallography for routine room-temperature structure determination at synchrotrons

open access: yesNature Communications, 2017
Serial crystallography was developed for protein crystal data collection with X-ray free-electron lasers. Here the authors present several examples which show that serial crystallography using high-viscosity injectors can also be routinely employed for ...
