We describe the Polarization Synchrotron, an experimental implementation of a superluminal (faster than light in vacuo) polarization current distribution that both oscillates and undergoes centripetal acceleration. The prototype machine produces tightly-beamed monochromatic radiation in the 100s of MHz range. The technique should also have applications as a broad-band GHz-THz source.
