We present a study of intra-beam scattering (IBS) in high-brightness electron beams, incorporating a recent theory that accounts for enhanced temporal correlations of electric field fluctuations. These correlations, absent in conventional binary-collision models, arise from the periodic betatron motion of particles within the beam. To enable direct verification of the theoretical calculations,...
Our work addresses the challenge of estimating spin po-
larization in high-energy electron and positron storage rings,
such as the Electron Storage Ring (ESR) of the Electron-Ion
Collider (EIC) at Brookhaven National Lab (BNL) and those
in the electron/positron Future Circular Collider (FCC-ee)
at CERN. We model the spin and orbital motion of particle
bunches using the recently...
Understanding and characterizing collective instabilities is critical for high-intensity operation at the Fermilab Recycler Ring. This work presents an application of the the Nested Head-Tail (NHT) formalism for modeling single-bunch transverse instabilities, incorporating analytical solutions to the resistive wall and theta wake impedances in the absence of space charge. Predicted growth...
