Specialists from the Institute of Applied Physics of the Russian Academy of Sciences have developed the first high-precision mirrors made of single-crystal silicon in Russia for synchrotron radiation.
The scientists' development has an ultra-smooth surface and roughness at the atomic level, ensuring shape accuracy down to 1 nm. The mirrors are designed for use at 4th generation synchrotron stations and free electron lasers.
The new mirrors can withstand high heat loads and provide high-quality reflection of powerful X-ray beams, allowing focused beams of hundreds of nanometers in size to be obtained. In the future, it is planned to increase the size of the mirrors to one meter and increase the accuracy to 0.5 nm, which will significantly expand the capabilities of researchers.
The results of the work will be in demand in the creation of X-ray radiation collectors for projection lithography.
