Relativistic charged particle beams, circulating in a storage ring, emit synchrotron radiation, which carries information about the granular structure of the beam. With modern instrumentation and techniques, we are now learning how to use this information to study and, also, to manipulate particle beams at sub-micrometer scales. In this talk we will describe a series of experiments, carried out in the Fermilab IOTA storage ring with single- and many-electrons as well as several combinations of undulators and optical devices. The experiments were designed to shed some "light" onto the fundamental and applied questions of these radiation techniques. We will describe several practical applications: the use of radiation fluctuations to determine the electron beam properties in a storage ring and the first ever demonstration of a novel beam cooling method, Optical Stochastic Cooling, which relies on detailed understanding and precise control of beam radiation. We will also discuss the future directions of these experiments.
