One possible explanation for the difference between matter and antimatter asymmetry may lie in CP-violation, which can be detected through the presence of a permanent electric dipole moment (EDM) in subatomic particles. To measure the EDM of charged particles with high accuracy, a state-of-the-art technique called "frozen spin" can be employed in an accelerator. The EDM experiment consists of three stages: initially using the magnetic ring COSY (Cooler Synchrotron Storage Ring at Forschungszentrum Juelich), followed by a prototype EDM ring, and ultimately the all-electric EDM ring. The intermediate ring serves as a replica of the final ring, enabling the investigation of different systematic effects while incorporating the fundamental principles of the final design. For the prototype EDM ring, simulations of beam dynamics are conducted using various lattices to optimize beam lifetime and minimize systematic effects. The initial design of the prototype EDM ring facilitated the estimation of beam losses using analytical formulas. Ongoing research endeavors strive to enhance the precision of EDM measurements and reduce systematic effects.

very compact bibliographies which can be beneficial to authors and
readers, and in "proceeding" format
which is more detailed and complete.
