A new way to make X-rays

By using plasmons to “wiggle” a free electron in a sheet of graphene, researchers have developed a new method for generating X-rays. In this image of one of their simulations, the color and height represent the intensity of radiation (with blue the lowest intensity and red the highest), at a moment in time just after an electron (grey sphere) moving close to the surface generates a pulse.

MIT researchers have found a phenomenon that might lead to more compact, tunable X-ray devices made of graphene. << more >>
