"The keys to RLE’s success have been an insistence on fundamental understanding, an openness to multiple viewpoints, the tight coupling of theory and experiment, motivation through a focus on applications, and an ongoing interaction between the development of probe techniques and the discovery of new phenomena."

A new way to make X‑rays

posted November 23, 2015 at 6:21 pm

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 »
