Characterization of a piezo bendable X-ray mirror [PDF]
Journal of Synchrotron Radiation, 2016 A full-scale piezo bendable mirror built as a prototype for an offset mirror at the European XFEL is characterized. The piezo ceramic elements are glued onto the mirror substrate, side-face on with respect to the reflecting surface. Using a nanometre optical component measuring machine and a large-aperture Fizeau interferometer, the mirror profile and ...

Thermal loading on crystals in an x-ray free-electron laser oscillator
Physical Review Accelerators and Beams, 2020 X-ray free electron laser oscillators (XFELOs) are future light sources that produce fully coherent hard x-ray pulses. Based on the low-gain principle, the XFELO traps x-ray pulses in an optical cavity composed of multiple Bragg-reflecting mirrors that ...

An x-ray regenerative amplifier free-electron laser using diamond pinhole mirrors
New Journal of Physics, 2019 X-ray free-electron lasers (FELs) rely on SASE due to the lack of seed lasers and the difficulty in obtaining mirrors. Progress in diamond crystal Bragg mirrors enables the design of x-ray FEL oscillators.
