Characterization of cryo‐cooled silicon crystal monochromators via measurement of flux versus power

Journal of Synchrotron Radiation, EarlyView.
The resilience of recently upgraded double‐crystal monochromators under increasing power load at Diamond Light Source is discussed. Experimental evidence and modelling are described.A study on the thermal load of cryogenically cooled silicon in synchrotron double‐crystal monochromators is presented, based on experimental data from four different ...

A versatile framework for attitude tuning of beamlines at light source facilities

Journal of Synchrotron Radiation, EarlyView.
A versatile Mamba‐based software framework for automated attitude tuning of beamlines is reported, which is expected to be able to cover most attitude‐tuning needs (beam focusing, sample alignment etc.) in a simple and maintainable way. As well as a few real‐world examples at the High Energy Photon Source and Beijing Synchrotron Radiation Facility ...

LeafGen: Leaf generation in 3D tree models

Methods in Ecology and Evolution, EarlyView.
Abstract Leaves are crucial for tree growth, survival and interaction with the environment. The spatial arrangement of leaves within the tree canopy significantly influences tree‐environment interactions, such as sunlight capture, scattering and shading, as well as rainfall interception.

A Framework for Iterative Phase Retrieval Technique Integration into Atmospheric Adaptive Optics—Part II: High Resolution Wavefront Control in Strong Scintillations

Photonics
In this paper, we introduce atmospheric adaptive optics (AO) system architectures that utilize scintillation-resistant wavefront sensors based on iterative phase retrieval (IPR) techniques (described in detail in Part I) for closed-loop mitigation of ...
