Diamond gratings let the X-ray pulses in and out (IMAGE)
Caption
Precision diamond gratings (orange and green squares) are used to bring X-rays in and out of the X-ray cavity. Room light bouncing off their intricately etched nanostructure produces the colors we see, much as water droplets in the atmosphere refract light into rainbows. The colors of the gratings change when viewed from different angles.
