Abstract:
In a lepton storage ring of very high energy (e.g. in the e+e− Higgs factory) synchrotron radiation from quadrupoles constrains transverse dynamic aperture even in the absence of any magnetic nonlinearities. This was observed in tracking for LEP [1] and the Future Circular e+e− Collider (FCCee) [2]. Synchrotron radiation in the quadrupoles modulates the particle energy at the double betatron frequency. Energy
modulation varies transverse focusing strength at the same frequency and creates a parametric resonance of the betatron oscillations with unusual properties [3]. It occurs at arbitrary betatron frequency and the magnitude of the parameter modulation of the betatron oscillation depends on the oscillation amplitude. Equilibrium between the radiation damping and the resonant excitation gives the boundary of the stable motion. Here we continue comparison of tracking results with analytical calculations of the parametric resonance.
