BAGELS: A General Method for Minimizing the Rate of Radiative Depolarization in Electron Storage Rings
Matthew G. Signorelli, Yunhai Cai, Georg H. Hoffstaetter de Torquat
We present a novel method for minimizing the effects of radiative depolarization in electron storage rings by use of vertical orbit bumps in the arcs. Electron polarization is dire…
A Feasibility Study of an e+e- Ring Collider for Higgs Factory
Yunhai Cai, Alex Chao, Yuri Nosochkov +2
A ring-based Higgs factory with a center-of-mass energy of 240 GeV residing in the existing LEP tunnel is studied at a level of concrete lattice. We found that low-emittance lattic…
Combined phase space characterization at the PEP-II IP using single-beam and luminous-region measurements
A. Bevan, W. Kozanecki, B. Viaud +5
We present a novel method to characterize the e+/- phase space at the IP of the SLAC B-factory, that combines single-beam measurements with a detailed mapping of luminous-region ob…
Simulation of Beam-Beam Effects in Storage Rings
Yunhai Cai
The beam-beam effects of the PEP-II as an asymmetric collider are studied with strong-strong simulations using a newly developed particle-in-cell (PIC) code. The simulated luminosi…
Simulation of the Beam-Beam Effects in Storage Rings with a Method of Reducing the Region of Mesh
Yunhai Cai, Alex W. Chao, Stephan I. Tzenov +1
A highly accurate self-consistent particle code to simulate the beam-beam collision in storage rings has been developed. It adopts a method of solving the Poisson equation…
Luminosity of Asymmetric e+e- Collider with Coupling Lattices
Yunhai Cai
A formula of luminosity of asymmetric e+e- collider with coupled lattices is derived explicitly. The calculation shows how the tilted angle and aspect ratio of the beams affect the…
