Tagged bremsstrahlung polarization: A Monte-Carlo approach

We present a Monte-Carlo approach for the determination of the degree of polarization of tagged bremsstrahlung. Our method allows the evaluation of the Bethe-Heitler expression in the photon-oriented reference system, while defining the photon and electron collimators in the spectrometer coordinate system. This avoids the need to perform fourfold integrals of complicated and bulky expressions. We reproduced the published calculations and measurements, and studied the polarization behavior as a function of several parameters in different geometric conditions.
