Development of high performance and large size X-ray multilayer reflective optics
X-ray multilayers are key optical elements in synchrotron radiation and free electron laser facilities, astronomical observations, plasma diagnostics, and lab-based analytical instruments. They can realize highly efficient reflection, monochromatization, and polarization of X-rays. Our group has been conducting systematic studies on the design, fabrication, and characterization of X-ray multilayers during the past 20 years. We have developed a series of high-performance multilayers with world-class level reflectivity at different wavelengths and have built the deposition platform for large size X-ray multilayers based on the magnetron sputtering technique. The largest deposition mirror could achieve a length of 1.2 m. The fabricated, hard X-ray multilayer mirrors have been successfully applied in synchrotron radiation facilities both in China and abroad. Through the combination of multilayer and reflective gratings, innovative, ultrahigh efficiency, tender, X-ray multilayer grating optics have been developed. Compared with conventional single-layer gratings, a maximum efficiency improvement of 40 times could be achieved. This study will introduce the results and progress that were achieved by our group in X-ray multilayer elements.
