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…
Injection Optimization at Particle Accelerators via Reinforcement Learning: From Simulation to Real-World Application
Awal Awal, Jan Hetzel, Ralf Gebel +1
Optimizing the injection process in particle accelerators is crucial for enhancing beam quality and operational efficiency. This paper presents a framework for utilizing Reinforcem…
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…
Optimization of the injection beam line at the Cooler Synchrotron COSY using Bayesian Optimization
A. Awal, J. Hetzel, R. Gebel +2
The complex non-linear processes in multi-dimensional parameter spaces, that are typical for an accelerator, are a natural application for machine learning algorithms. This paper r…
Spin Physics at COSY (2021-2024 and beyond) -- Pathfinder investigations toward an EDM storage ring and Spin-for-FAIR
R. Gebel, V. Hejny, A. Kacharava +24
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 f…
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.…
