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

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

Quadrupole Beam-Based Alignment at RHIC

Successful implementation of a beam-based alignment algorithm, tailored to different types of quadrupoles at RHIC, provides significant benefits to machine operations for heavy ions and polarized

Measurement of the Permanent Electric Dipole Moment of the Neutron.

We present the result of an experiment to measure the electric dipole moment (EDM) of the neutron at the Paul Scherrer Institute using Ramsey's method of separated oscillating magnetic fields with

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,

Search for Electric Dipole Moments of Charged Particles with Polarized Beams in Storage Rings

The observation of a non zero electric dipole moment of a fundamental particle would represent a clear sign of New Physics beyond the Standard Model. An experimental program is presently pursued by
