Abstract

We present the results of the first measurement of the rocking curve of a nanofocusing compound refractive lens made of silicon, used for focusing synchrotron radiation (SR) at the "KISI-Kurchatov" source. The obtained curve is accurately approximated by a Gaussian function, and its width agrees with a previously developed analytical theory describing SR propagation in multi-element focusing systems. The results demonstrate the feasibility of using the rocking curve as an alignment characteristic of the experimental setup when working with silicon lenses at second-generation SR sources.
