Electro-Optic Sampling of Transient Fields from the passage of High-Charge Electron Bunches
M. J. Fitch, A. C. Melissinos, P. L. Colestock +3
When a relativistic electron bunch traverses a structure, strong electric fields are induced in its wake. We present measurements of the electric field as a function of time as mea…
The Beam Halo Experiment at the LEDA Facility
P. L. Colestock, T. Wangler, C. K. Allen +6
Due to the potentially adverse effects of the generation of halo particles in intense proton beams, it is imperative to have a clear understanding of the mechanisms that can lead t…
Coherent Nonlinear Phenomena in High Energy Synchrotrons: Observations and Theoretical Models
P. L. Colestock, L. K. Spentzouris, S. I. Tzenov
Nonlinear waves have been observed in synchrotrons for years but have received little attention in the literature. While pathological, these phenomena are worth studying on at leas…
Solitary Waves on a Coasting High-Energy Stored Beam
S. I. Tzenov, P. L. Colestock
In this work we derive evolution equations for the nonlinear behavior of a coasting beam under the influence of a resonator impedance. Using a renormalization group approach we fin…
