Dynamic Focusing to Suppress Emittance Transfer in Crab-Crossing Flat Beam Collisions
Derong Xu, J Scott Berg, Michael M Blaskiewicz +8
Flat hadron beam collisions, though expected to enhance peak luminosity by about an order of magnitude, have not yet been demonstrated. Our study reveals a critical limitation: rea…
Advancing Electron Injection Dynamics and Mitigation Approaches in the Electron-Ion Collider Swap-out Injection Scheme
Derong Xu, Ferdinand Willeke, Michael M. Blaskiewicz +2
The Electron-Ion Collider (EIC) will use swap-out injection scheme for the Electron Storage Ring (ESR) to overcome limitations in polarization lifetime. However, the pursuit of hig…
Assessing global crabbing scheme feasibility for Electron-Ion Collider
Derong Xu, Yun Luo, Daniel Marx +1
The Electron-Ion Collider (EIC) plans to utilize the local crabbing crossing scheme. This paper explores the feasibility of adopting a single crab cavity with adjusted voltage, ins…
Enhanced beam-beam modeling to include longitudinal variation during weak-strong simulation
Derong Xu, Vasiliy S. Morozov, David Sagan +2
Beam-beam interactions pose substantial challenges in the design and operation of circular colliders, significantly affecting their performance. In particular, the weak-strong simu…
