Resonant Island Trapping in a Fourth-Generation Synchrotron Light Source

We report the first direct observation of nonlinear resonance island trapping in a fourth-generation light source with working points far from the excited resonance and examine the nonlinear dynamics and properties of the trapped beam. The discovered dynamics of island trapping may help understand bunch purity and halo formation issues, create additional experimental capabilities for photon science applications, and present means of nonlinear characterization of the machine optics.

Design of a resonant slow extraction from low emittance electron booster rings using transverse resonance island buckets

In this contribution we present the design of a resonant slow extraction based on the radio frequency knock-out (RF-KO) scheme, where we make use of the transverse resonance islands bucket (TRIB) optics. The generation of the TRIB optics is presented in two example lattices, that are considered for the potential upgrade of the current booster at DESY. The slow extraction would potentially supply high energy electron beams to the HEP beamline users. Simulations show an extraction efficiency in excess of 90% with a septum blade thickness of \SI{100}{\micro\meter}.

Interpretation of the horizontal beam response near the third integer resonance

The beam response to an external periodic excitation delivers relevant information about the optics, tune distribution and stability of a circulating beam in a storage ring. In this contribution the horizontal beam response to the excitation (transfer function) under conditions typical for slow extraction is presented for a coasting beam. The resulting spectrum exhibits a splitting behaviour. The single particle dynamics is discussed and an interpretation based on simulation results is presented.
