On Possibilities of High Precision Fundamental Physics Experiments in Spin-Transparent Storage Rings of Low Energy Polarized Electron Beams
arXiv:2105.11575 · doi:10.1016/j.physletb.2023.138058
Abstract
We 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 can be measured using standard Mott Polarimetry that is optimal at low electron energy. Systematic uncertainties are suppressed using counter-rotating bunched beams with various polarization orientations. These rings can be used to directly measure the permanent electric dipole moment of the electron, relevant to CP violation and matter-antimatter asymmetry in the universe, and to search for dark energy and ultra-light dark matter.
