Science Daily — A team of researchers at the U.S. Department of Energy’s Brookhaven National Laboratory have overcome a major obstacle for using refractive lenses to focus x-rays. This method will allow the efficient focusing of x-rays down to extremely small spots and is an important breakthrough in the development of a new, world-leading light source facility that promises advances in nanoscience, energy, biology, and materials research.

At Brookhaven’s National Synchrotron Light Source (NSLS), the scientists exceeded a limit on the ability to focus “hard,” or high-energy, x-rays known as the “critical angle.”
