A formalism for deriving the power spectrum of this phenomenon in the ultrarelativistic classical regime was developed in 1945 by Julian Schwinger, who noted that its power spectrum increases up to a critical frequency, after which it declines exponentially. The angular distribution of power due to this phenomenon is concentrated in a cone with angle inversely proportional to the (*) gamma factor, and in the relativistic regime, this phenomenon is strongly polarized in the plane of motion. The total energy produced by this phenomenon is proportional to the fourth power

The angular distribution of power due to this phenomenon is concentrated in a cone with angle inversely proportional to the (*) gamma factor, and in the relativistic regime, this phenomenon is strongly polarized in the plane of motion. The total energy produced by this phenomenon is proportional to the fourth power of gamma, and it is commonly produced using periodic magnetic fields created by structures called undulators. For 10 points, identify this phenomenon, the radiation produced by a radially accelerated charged particle.
