Investigation of beam self-polarization in the future $e^{+}e^{-}$ circular collider (1705.03003v1)
Published 5 May 2017 in physics.acc-ph
Abstract: The use of resonant depolarization has been suggested for precise beam energy measurements (better than 100 keV) in the $e{+}e{-}$ Future Circular Collider (FCC-$e{+}e{-}$) for Z and WW physics at 45 and 80 GeV beam energy respectively. Longitudinal beam polarization would benefit the Z peak physics program; however it is not essential and therefore it will be not investigated here. In this paper the possibility of self-polarized leptons is considered. Preliminary results of simulations in presence of quadrupole misalignments and beam position monitors (BPMs) errors for a simplified FCC-$e{+}e{-}$ ring are presented.
