I believe that your theory needs realism by being involved and being in close touch with experimentalists... Don't stray far from the experiments if you are working on theory, and if you have talent for experiments, do them."

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 »
