2 00 1 Simulation of Beam - Beam Effects in e + e − Storage Rings ∗
نویسنده
چکیده
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[1]. The simulated luminosity agrees with the measured one within 10% in a large range of the beam currents. The spectra of coherent dipole oscillation are simulated with and without the transparency symmetry. The simulated tune shift of the coherent π mode agrees with the linearized Vlasov theory even at large beam-beam parameters. The Poicare map of coherent dipole is used to identify the beam-beam resonances.

Simulations and Experiments of Beam - Beam Effects in e + e − Storage Rings ∗
Over the past decade, extensive simulations of beam-beam effects in e+e− colliders, based on the particle-in-cell method, were developed to explain many complex experimental observations. Recently, such simulations were used to predict the future luminosity performance of e+e− colliders. Some predictions have been proven to be correct in the existing accelerators. In this paper, many effects su...
متن کاملEffect of Electron Beam Irradiation on Survival of Escherichia coli O157:H7 and Salmonella enterica serovar Thyphimurium in Minced Camel Meat during Refrigerated Storage
Background: Electron beam irradiation is one of the effective ways to control food-borne pathogens. We evaluated the effect of electron beam irradiation on survival of Escherichia coli O157:H7 and Salmonella enterica serovar Thyphimurium in minced camel meat during refrigerated storage. Methods: The meat samples were inoculated with E. coli O157:H7 and S. enterica serovar Thyphimurium and then...
متن کاملOdysseus: a Dynamic Strong-strong Beam-beam Simulation for Storage Rings
We have developed a simulation of the beam-beam interaction in e+/estorage ring colliders which is specifically intended to reveal the dynamic collective behavior of the colliding beams. This program is a true 6-dimensional strongstrong simulation in which the electromagnetic fields of longitudinal slices of the colliding beams are recalculated for each slice collision. Broadband wake fields ar...
متن کاملSPIN MOTION IN e + e - STORAGE RINGS
General properties of the spin motion in e+estorage rings are studied in order to determine the conditions where radiative beam polarization is likely to occur. A general first-order theory of depolarization is developed and applied to specific examples of nonresonant , depolarization in storage rings. It is found that under many practical conditions radiative beam polarization should occur and...

This study investigates the effect of different link beam lengths in the Reinforced Concrete (RC) frame retrofitted with the Linked Column Frame (LCF) system. It also investigates the ratio of the link beam length (e) to the span length of the RC frame (L) from 0 to 1.5 for the 9 models of the RC frame retrofitted by the LCF system has been investigated. In addition, it studies the formation of...
