Imperfections in the Crab-Waist Scheme
Demin Zhou
The crab-waist collision scheme has been the baseline choice for SuperKEKB and future circular colliders. Achieved through properly phased sextupoles, the crab-waist trans…
Beam Dynamics Issues in the SuperKEKB
Demin Zhou, Haruyo Koiso, Akio Morita +3
This article reviews the beam dynamics issues, such as intra-beam scattering, beam-beam interaction, lattice nonlinearity, and space charge, in SuperKEKB before its commissioning.
General formulation of impedance in Frenet-Serret coordinate system
Demin Zhou, Cheng-Ying Tsai
In accelerator physics, the concept of impedance is popularly used to describe the interactions of charged particles inside a bunch or between bunches in a train. Standard formulat…
Generalized Panofsky-Wenzel theorem in curvilinear coordinate systems applicable to non-ultrarelativistic beams
Demin Zhou, Cheng-Ying Tsai
This note gives an introduction to the theories of impedances and wakes in particle accelerators. The standard formulation assumes that the beam is traveling along a straight orbit…
Potential-well bunch lengthening in electron storage rings
Demin Zhou, Gaku Mitsuka, Takuya Ishibashi +1
The cubic equation derived by B. Zotter has been popularly used for electron storage rings to describe the scaling law of potential-well bunch lengthening. This equation has also o…
Luminosity performance of SuperKEKB
Demin Zhou, Kazuhito Ohmi, Yoshihiro Funakoshi +1
Since April 2020, the SuperKEKB has been operating with the crab waist scheme. The luminosity record achieved in June 2022 was , w…
