Synchrotron radiation models for spin tracking in circular accelerators — •Jan Schmidt, Oliver Boldt, and Wolfgang Hillert — Elektronen-Stretcher-Anlage ELSA, Physikalisches Institut, Universität Bonn

Polarized beams are useful for high-energy physics and hadron physics experiments. The polarization of leptons in circular accelerators is affected significantly by synchrotron radiation. The implementation of these radiation effects in a spin tracking algorithm considerably increases computing times. This is due to the statistical nature of synchrotron radiation and the need to track many particles to compute beam polarization.

Thus, simplified models of the influence of radiation on the particle motion in longitudinal phase space are crucial for efficient spin dynamics studies. In this talk different models are discussed concerning their effect on spin dynamics. These investigations have been made possible by the new spin dynamics simulation suite POLE - and elegant, a 6D accelerator simulation code including synchrotron radiation.
