Maintaining a Resonance Condition of an RF Spin Rotator Through a Feedback Loop in a Storage Ring
V. Hejny, A. Andres, J. Pretz +63
This paper presents the successful application of a phase-lock feedback system to maintain the resonance condition of a radio frequency (rf) spin rotator (specifically, an rf Wien…
Pilot bunch and co-magnetometry of polarized particles stored in a ring
J. Slim, F. Rathmann, A. Andres +60
In polarization experiments at storage rings, one of the challenges is to maintain the spin-resonance condition of a radio-frequency spin rotator with the spin-precessions of the o…
Spin decoherence and off-resonance behavior of radiofrequency-driven spin rotations in storage rings
N. N. Nikolaev, F. Rathmann, J. Slim +60
Radiofrequency-driven resonant spin rotators are routinely used as standard instruments in polarization experiments in particle and nuclear physics. Maintaining the continuous exac…
First Search for Axion-Like Particles in a Storage Ring Using a Polarized Deuteron Beam
Swathi Karanth, Edward J. Stephenson, Seung Pyo Chang +60
Based on the notion that the local dark-matter field of axions or axion-like particles (ALPs) in our Galaxy induces oscillating couplings to the spins of nucleons and nuclei (via t…
First detection of collective oscillations of a stored deuteron beam with an amplitude close to the quantum limit
J. Slim, N. N. Nikolaev, F. Rathmann +41
We investigated coherent betatron oscillations of a deuteron beam in the storage ring COSY, excited by a detuned radio-frequency Wien filter. The beam oscillations were detected by…
Beam-based alignment at the Cooler Synchrotron COSY as a prerequisite for an electric dipole moment measurement
T. Wagner, A. Nass, J. Pretz +47
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.…
