In the frame of the LEAPS-Innov pilot project, the ESRF together with ALBA, Soleil, PTB and HZB have developed a position measuring system based on fibered laser interferometers and beam steering mirrors that track the position of the object to be measured thanks to a closed loop control system. The global objective is to measure the position of objects moving in a plane along 3 degrees of...
This contribution provides an insight into the X-ray Free Electron Laser Oscillator (XFELO), an R&D project currently under commissioning at the European XFEL. XFELO aims to be the first demonstrator of a cavity-based free electron laser, promising significantly enhanced beam properties. The layout of the optical cavity and its integration into the SASE1 undulator section present unique...
Coupled with faster detectors, X-ray optic upgrades, new flagship beamlines, and advanced data pipelines, the new low emittance Diamond-II source will benefit a wide range of scientific communities. Smaller, brighter, X-ray beams enable sample scanning systems to progress from slow, step-based motion to rapid, freeform dynamic trajectories. Metrology feedback devices, such as interferometers...
The Precision Metrology Laboratory (PML) at Diamond Light Source provides an ultra-stable environment and instrumentation to perform micro- to nano- scale dimensional metrology to support beamline operation. The lab is actively stabilised to ± 10 mK in temperature and ± 0.5 %RH in humidity. Under these conditions, sub-nm displacements have been measured using capacitive sensor and linear...
