Two of the major scientific drivers of particle physics and cosmology are the faith of antimatter after the Big Bang and the origin of Dark Matter. The answers to these questions can be addressed by investigating permanent and oscillating Electric Dipole Moments (EDM) of fundamental particles. The experiments can be performed with polarized beams in a storage rings. Important milestones have...
We will present a new design of highly specialized small storage rings for low energy polarized electron beams. The new design is based on the transparent spin methodology that cancels the spin precession due to the magnetic dipole moment at any energy while allowing for spin precession induced by the fundamental physics of interest to accumulate. The buildup of the vertical component of beam...
Polarization of proton beam in the Brookhaven Alternating Gradient Synchrotron is preserved during acceleration by use of two helical dipole partial snake magnets. These magnets modify the spin tune to avoid strong intrinsic resonances associated with the vertical betatron motion, but in the process excite many weaker resonances associated with the horizontal betatron motion. Since these...
The Electron Ion Collider (EIC) represents a cutting-edge facility designed to explore the internal structure of protons and atomic nuclei at unprecedented levels. In this study, we focus on the investigation of the influence of crab cavities within the EIC setup on the polarization.
Crab cavities play a crucial role in achieving head-on collisions between particle bunches, enhancing...
