Synchrotron radiation is the electronmagnetic radiation emitted by electrons or positrons moving at relativistic velocities along a curved trajectory with a large radius of curvature."Large" here implies that quantum effects are negligible,while they are not.The name itself,"synchrotron" radiation, derives from one specific type of accelerator, the electron synchrotron.
