Synchrotron Radiation and Pretzeled Orbits Geometry of Synchrotron Radiation Illumination

Turning on a `pretzel' , or any closed orbit distortion, can substantially alter the path of synchrotron radiation (SR), in some instances causing it to strike components not designed to absorb the radiation. In this paper I develop equations useful in determining the source position and angle of dipole SR as a function of the pretzel amplitude and angle. Formula for linear power deposition and...

Electroweak Synchrotron Radiation*

We calculate the emission rate and spectrum for radiation of neutral electroweak bosons (Z”) f rom an electron in a weak external homogeneous electromagnetic field satisfying 1 f Fcly Fp”/1/2 < Fc 3 mzc3/eti. The calculational method is based on the source theory formulation of quantum field theory introduced by Schwinger. In particular for ultra-relativistic electrons, we find that the 2’ emis...
