First Experimental Demonstration of Reinforcement Learning-Based Tuning on the PSI Injector 2 Cyclotron
M. Haj Tahar, W. Joho, E. Solodko +7
Reliable operation of high-power proton cyclotrons is a critical requirement for Accelerator Driven Systems (ADS) and other large-scale applications. Beam tuning in such machines i…
Probing the losses for a high power beam
M. Haj Tahar, D. Kiselev, A. Knecht +3
The High Intensity Proton Accelerator (HIPA) cyclotron at the Paul Scherrer Institut (PSI) delivers 590 MeV CW proton beam with a maximum power of 1.42 MW. After extraction, the be…
Report of the Snowmass'21 Workshop on High-Power Cyclotrons and FFAs
Daniel Winklehner, Andreas Adelmann, Jose R. Alonso +4
This whitepaper summarizes and the state of the field of high-power cyclotrons and FFAs as discussed by international experts during a three-day workshop of the same name. The work…
Systematic error studies for the charged particle EDM measurement proposal
M. Haj Tahar, C. Carli
Proposals aimed at measuring the Electric Dipole Moment (EDM) for charged particles require a good understanding of the systematic errors that can contribute to a vertical spin bui…
Storage Ring to Search for Electric Dipole Moments of Charged Particles -- Feasibility Study
F. Abusaif, A. Aggarwal, A. Aksentev +98
The proposed method exploits charged particles confined as a storage ring beam (proton, deuteron, possibly He) to search for an intrinsic electric dipole moment (EDM) aligned a…
On solving the Thomas Bargman-Michel-Telegdi equation using the Bogoliubov Krylov method of averages and the calculation of the Berry phases
Malek Haj Tahar, Christian Carli
Several proposals aimed at measuring the Electric Dipole Moment (EDM) for charged particles require very precise simulations and understanding of the systematic errors that can con…

F. Abusaif, A. Aggarwal, A. Aksentev +92
This project exploits charged particles confined as a storage ring beam (proton, deuteron, possibly He) to search for an intrinsic electric dipole moment (EDM, ) aligne…
Racetrack Fixed Field Accelerator with pulsed quadrupoles for variable energy extraction
Malek Haj Tahar, David J. Brenner, Gerhard Randers-Pehrson
In this paper, a novel concept combining a fixed field alternating gradient accelerator with time-varying quadrupoles is presented which solves some of the major problems of conven…
Tune compensation in nearly scaling Fixed Field alternating gradient Accelerators
Malek Haj Tahar, François Méot
In this paper, we investigate the stability of the particle trajectories in Fixed Field alternating gradient Accelerators (FFA) in the presence of field errors: The emphasis is on…
Characterization techniques for fixed-field alternating gradient accelerators and beam studies using the KURRI 150 MeV proton FFAG
S. L. Sheehy, D. J. Kelliher, S. Machida +9
In this paper we describe the methods and tools used to characterize a 150 MeV proton scaling Fixed Field Alternating Gradient (FFAG) accelerator at Kyoto University Research React…
