MEMS Mirror (IMAGE) DOE/Argonne National Laboratory Caption Scientists at Argonne have created a new way of manipulating high-intensity X-rays, which will allow researchers to select extremely brief but precise X-ray bursts for their experiments. This schematic of their microelectromechanical device consisting of a small oscillating mirror illustrates the reflection of an incoming X-ray at a particular critical angle.
