A Kick Experienced by a Particle Obliquely Traversing a Bunch
نویسندگان
چکیده
Crossing of bunches at an angle in a storage ring is studied. A case when a particle trajectory intersects the opposing bunch off-center and at an angle to the main axis of the bunch charge distribution is considered. Formulae for a kick experienced by a particle are derived for crossing in both horizontal and vertical planes. This kick is a function of the off-center distance in the longitudinal direction and the crossing angle. In such a geometry, synchro-betatron resonances can be excited. The resonance width is proportional to the derivative of the kick over the longitudinal distance from the bunch center. The magnitude of this derivative is evaluated in detail.

Crossing Angle Collision and Lifetime: Simulations, Analysis, Measurements and More Simulations
The introduction of a crossing angle in e+ecolliders causes nonlinear coupling between horizontal motion and longitudinal motion. This is illustrated in Figure 1. The beam-beam kick occurs when the particle passes the center of the opposing bunch. The strength of the kick, ∆r' = F(r), is a nonlinear function of the distance, r, between the particle and the center of the opposite bunch. In head-...

متن کاملBunch-by-Bunch Feedback for PEP II*
The proposed PEP II B factory at SLAC requires a feedback to damp out longitudinal synchrotron oscillations. A time domain, downsampled, bunch-by-bunch feedback system in which each bunch is treated as an oscillator being driven by disturbances from other bunches is presented as we review the evolution of the system design. Results from a synchrotron oscillation damping experiment conducted at ...

This paper discusses various aspects of multibunch motion in thepresence of nearest neighbor wakefield coupling. Included are the solution to the problem for smooth focusing with equal bunch energies, an explanation for the apparent &mping of the bunch amplitudes that is observed for weak coupling, and a treatment of the problem for discrete focusing based on the moments of the wakefield distri...

A multi-bunch beam, traversing travelling wave accelerator structures, each with a 5π/6 phase advance per cell, is accelerated at a frequency that is synchronous with the fundamental mode frequency. As per design, the main interaction occurs at the working frequency of 11.424 GHz. However, modes with frequencies surrounding the dominant accelerating mode are also excited and these give rise to ...
