The Jülich Electric Dipole moment Investigation (JEDI) collaboration aims at a direct measurement of the Electric Dipole Moment (EDM) of protons and deuterons using a storage ring. The measurement is based on a polarization measurement. In order to reach highest accuracy, one has to know the exact trajectory through the magnets, especially the quadrupoles, to avoid the influence of magnetic fields on the polarization vector. In this paper, the development of a beam-based alignment technique is… 

Spin Physics at COSY (2021-2024 and beyond) -- Pathfinder investigations toward an EDM storage ring and Spin-for-FAIR

The unique global feature of COSY is its ability to accelerate, store and manipulate polarized proton and deuteron beams. In the recent past, these beams have been used primarily for precision

Storage Ring to Search for Electric Dipole Moments of Charged Particles -- Feasibility Study

The proposed method exploits charged particles confined as a storage ring beam (proton, deuteron, possibly helium-3) to search for an intrinsic electric dipole moment (EDM) aligned along the particle

Beam Based Alignment of the Beam Position Monitor at J-PARC RCS

The J-PARC RCS is a Mega-Watt class rapid cycling synchrotron and it delivers an intensive beam to the neutron target and the MR. In order to handle large space charge, its physical aperture is

Automated beam based alignment of the ALS quadrupoles

Knowing the electrical offset of the storage ring beam position monitors (BPM) to an adjacent quadrupole magnetic center is important in order to correct the orbit in the ring. We describe a simple,
