Increased spatial coherence length from an asymmetric crystal reflection at grazing exit

Autor: Albert Macrander, Xianbo Shi, Walan Grizzoli, Xianrong Huang, Nino Pereira, Michael Wojcik, Lahsen Assoufid

Publikováno v: Journal of Synchrotron Radiation, Vol 31, Iss 3, Pp 508-516 (2024)

Coherent X-ray imaging is an active field at synchrotron sources. The images rely on the available coherent flux over a limited field of view. At many synchrotron beamlines a double-crystal monochromator (DCM) is employed in a standard nondispersive

Observation of critical scaling in spin glasses below Tc using thermoremanent magnetization

Autor: G. G. Kenning, M. Brandt, R. Brake, M. Hepler, D. Tennant

Publikováno v: Frontiers in Physics, Vol 12 (2024)

Time-dependent thermoremanent magnetization (TRM) studies have been instrumental in probing energy dynamics within the spin glass phase. In this paper, we review the evolution of the TRM experiment over the last half century and discuss some aspects

Exploring beam size measurement based on the Talbot effect at BEPCII

Autor: Wan Zhang, Dechong Zhu, Yanfeng Sui, Junhui Yue, Jianshe Cao, Jun He

Publikováno v: Journal of Synchrotron Radiation, Vol 30, Iss 5, Pp 910-916 (2023)

Vertical beam size measurements were carried out at Beijing Electron–Positron Collider II (BEPCII) using a phase grating and an absorption grating based on the Talbot effect. The transverse coherence of synchrotron radiation is closely related to b

Spin glass dynamics through the lens of the coherence length

Autor: J. He, R. L. Orbach

Publikováno v: Frontiers in Physics, Vol 12 (2024)

Spin glass coherence lengths can be extracted from experiment and from numerical simulations. They encompasses the correlated region, and their growth in time makes them a useful tool for exploration of spin glass dynamics. Because they play the role
