Researchers have developed a less expensive and more efficient way of controlling x-ray beams used to study the intricate details of batteries, solar cells, proteins and all manner of materials. The new beam-shaping devices can be made from a single piece of copper, which dramatically reduces the time and complexity of their construction – and their cost. Synchrotron light sources like NSLS-II produce very powerful beams of x-rays by wiggling the path of electrons speeding through a circular ring at 99.99 percent the speed of light.
