Description
This work examines a helical undulator, which serves as a source of polarized positrons. The fundamentals of undulator radiation and the influence of the associated parameters are discussed. It analyzes how the polarization transfer from the photons of the undulator radiation to the resulting positrons occurs and how the degree of polarization can be influenced.
Furthermore, the simulation program CAIN is used to examine its applicability for optimizing undulator parameters. In particular, simulations using CAIN are used to test how the collimator geometry influences the polarization and the positron yield. Specifically, an elliptical collimator geometry is considered.
