The fundamental principles behind the operation of a synchrotron are based in electromagnetic theory: when electrons moving at near the speed of light are subjected to a magnetic field, they can then be deflected to create strong radiation in a tangential direction--namely, synchrotron radiation.
它的原理是根據電磁學理論：當電子以接近光的速度飛行時，若受到磁場的作用而發生偏轉，便會在其切線方向放出極強的輻射光，這就是同步輻射光。
