Description
We propose a storage ring to search for electric dipole moments of charged particles with unprecedented sensitivity. This requires the design of a new type of accelerator namely an all-electric storage ring capable of simultaneously maintaining clockwise and counter-clockwise polarized beams – a prime task for the accelerator community. The EDM observable is embedded in the time development of the beam polarization, a quantity studied in many nuclear/hadron physics experiments. The scientific case rests upon non-electroweak CP-symmetry violation and the related strong CP-problem; additional CP-violation will elucidate the matter-antimatter asymmetry puzzle of the Universe, which falls into the realm of particle and astroparticle physics. Oscillating EDMs are an additional subject-of-study to search for axion/ALP Dark Matter, one further outstanding question of contemporary subatomic science.
