Surfaces are typically in a state of flux at the atomic level, undergoing processes that cover orders of magnitude in time scale. I will explain how the helium-3 surface spin echo experiment measures atomic-scale processes down to the picosecond regime (one million million events per second). As a recent and exciting application of the technique, I will present the first spin echo measurements of the diffusion of carbon on a metal surface during the growth of a single carbon layer (graphene).
