Abstract

Hard X-rays are high-energy photons with extremely short wavelengths of the order of atomic distances. Their short wavelengths allow hard X-rays to be focused to nanometer sizes. This concept is simple; however, it is technically difficult to implement. For this reason, many physicists have been investigating X-ray focusing. In this study, we produce a single-digit nanometer sized hard X-ray focal spot using an ultraprecise multilayer mirror. Such extremely narrow hard X-ray beams can be used to achieve extremely high spatial resolutions in various X-ray microscopy techniques. Coupled with the high pulse powers of X-ray free-electron lasers, such nanofocusing optics have the potential to exceed the Schwinger limit.
