Simulation of Inhomogeneous Refractive Index Fields Induced by Hot Tailored Forming Components
Advanced Engineering Materials, EarlyView.This article presents a simulation model for simulating inhomogeneous refractive index fields (IRIF) in hot‐forged components, accounting for thermal influences and complex geometries. Through this simulation, a priori knowledge about the propagation of the IRIF can be obtained, allowing for the positioning of the component or an optical measurement ...

Advanced Engineering Materials, EarlyView.Incorporating nanosized silver into titanium for antimicrobial materials exploits the metastable miscibility gap between silver and titanium. Silver nanoparticles are synthesized via pulsed laser ablation in liquid. Silver addition refines the microstructure, increases hardness by 30%, and reduces Staphylococcus capitis microbial adhesion by 70%, with ...

At-wavelength Metrology of X-ray Optics at Diamond Light Source
Optics & Photonics - Optical Engineering + Applications, 2013 Modern third-generation synchrotron radiation sources provide coherent and extremely bright X-ray beams, but the performance of the optics employed on the beamlines is critical for the X-rays' successful exploitation. The quality of the beam delivered to

High-resolution accelerator alignment using x-ray optics
Physical Review Special Topics. Accelerators and Beams, 2006 We propose a novel alignment technique utilizing the x-ray beam of an undulator in conjunction with pinholes and position-sensitive detectors for positioning components of the accelerator, undulator, and beam line in an x-ray free-electron laser.
