Zig-zagging device focuses high-energy radiation emissions

(Springer) Equipment used in cancer treatment requires a strong, monochromatic source of radiation to produce hard X-rays. Other similar radiation sources find applications in nuclear waste processing. To design devices that steadily emit a specific type of radiation, physicists use a special kind of crystal, referred to as a crystalline undulator. In astudy published in EPJ D, a team has demonstrated the ability to control radiation emissions from a particle traveling through such a device.
