Description

The University of Bonn operates a 3.2 GeV synchrotron capable of accelerating spin polarized electrons from a dedicated GaAs-source to external experimental stations. The facility's key capabilities include the mitigation of depolarizing resonances (tune jumps, harmonic correction) and polarimetry (stored and extracted beam). It offers unique opportunities for testing applications for future circular colliders, such as beam energy calibration schemes, spin preservation techniques and verification of simulation codes. In particular the development of a fast Compton polarimeter for enhanced precision in beam energy monitoring is of interest.
