A Unified Approach for Coupled Beam Optics in Accelerators
Onur Gilanliogullari, Brahim Mustapha, Pavel Snopok
Coupled beam optics can be geometrically described in terms of invariant eigenmode planes of a stable symplectic ``one-turn'' map . We show that the non-unique…
A Formalism for the Transport and Matching of Coupled Beams in Accelerators
Onur Gilanliogullari, Brahim Mustapha, Pavel Snopok
Understanding transverse coupling dynamics is crucial for beam physics, accelerator design, and operations. Currently, most accelerators are designed for uncoupled beams, and coupl…
Avoiding Beam Instabilities and Resonances With Circular Modes
Onur Gilanliogullari, Brahim Mustapha, Pavel Snopok
Beam instabilities and resonances affect the transverse dynamics in particle accelerators and, when encountered, can trigger emittance growth and beam loss. Resonance lines origina…
Circular Modes for Mitigating Space-Charge effects and enabling Flat Beams
Onur Gilanliogullari, Brahim Mustapha, Pavel Snopok
Flat beams are preferred in high-intensity accelerators and high-energy colliders due to one of the transverse plane emittances being much smaller than the other, which enhances lu…
Circular Modes for Linacs
Onur Gilanliogullari, Brahim Mustapha, Pavel Snopok
Circular mode beams are beams with non-zero angular momentum and strong inter-plane coupling. This coupling can be achieved in linear accelerators (linacs) through magnetization of…
Minimizing Space Charge Tune Spread and Increasing Beam Quality Parameters with Circular Modes
Onur Gilanliogullari, Brahim Mustapha, Pavel Snopok
Space charge has been a limiting factor for low energy accelerators inducing emittance growth and tune spread. Tune shift and tune spread parameters are important for avoiding reso…
