Paper Abstract

Adaptive angular control of reflecting crystals is crucial for reliable operation of high-resolution x-ray optics at synchrotron radiation facilities. An anglular compensation with nanoradian tolerance is required for some advanced applications. We present a working solution, a null-detection feedback system which was successfully applied for stabilization of an x-ray monochromator with energy resolution of ΔE/E ≈ 10−8(E = 23.7 keV). Another possible application of the feedback system, stabilization of optical cavity for x-ray free electron laser oscillator (XFELO) is discussed.
