- Martin Dommach (European X-Ray Free-Electron Laser)
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...
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...
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...
