Researchers at NIST and the University of Waterloo have developed a new microscopic device to improve how neutrons are used in scientific research. This innovation features tiny zebra-striped squares arranged on a silicon plate that act like a specialized filter for neutron beams. The technology was recently built and tested, establishing a new method to control how these waves travel.
Traditionally, neutron beams spread out quickly, which limits the detail scientists can observe in materials. This new structure twists the neutron waves to keep the beam focused for longer, effectively extending the researchers’ vision. The result is a more powerful tool for studying next-generation quantum materials and examining internal structures that are hard to see with standard X-rays.
