Bunch-by-bunch Detection of Coherent Transverse Modes from Digitized Single-bpm Signals in the Tevatron*
A system was developed for bunch-by-bunch detection of transverse proton and antiproton coherent oscillations based on the signal from a single beam-position monitor (BPM) located in a region of the ring with large amplitude functions. The signal is digitized over a large number of turns and Fourier-analyzed offline with a dedicated algorithm. To enhance the signal, the beam is excited with ban...
متن کاملElectron Bunch Profile Diagnostics in the Few Fs Regime Using Coherent Smith-purcell Radiation*
The rapid developments in the field of laser-driven particle acceleration hold the prospect of intense, highly relativistic electron bunches that are only a few fs long. The determination of the temporal profile of such bunches presents new challenges. The use of a radiative process such as Smith-Purcell radiation (SPR), is particularly promising in this respect. In this technique the beam is m...
متن کاملDiffraction Effects in Coherent Transition Radiation Diagnostics for Sub-mm Bunch Length Measurement*
Electrons crossing the boundary between different media generate bursts of transition radiation. In the case of bunches of N electrons, the radiation is coherent and has an N-squared enhancement at wavelengths related to the longitudinal bunch distribution. This coherent transition radiation has therefore attracted attention as an interceptive charged particle beam diagnostic technique. Many an...
متن کاملQuantum theory of coherent transverse optical magnetism
Density matrix theory is presented to explain recent experimental observations of intense optically induced magnetism due to a “mixed” type of nonlinearity proportional to the product of the electricand magnetic-field strengths of light. Two previously unknown quadratic optical effects are predicted—namely, transverse optical magnetization and magnetic charge separation—and quantitative agreeme...
متن کاملThomson scattering of coherent diffraction radiation by an electron bunch.
This paper considers the process of Thomson scattering of coherent diffraction radiation (CDR) produced by the preceding electron bunch in the accelerator onto one of the subsequent bunches. It is shown that the yield of scattered hard photons is proportional to N(3)(e), where N(e) is the number of electrons per bunch. A geometry is chosen for the CDR generation and an expression is obtained fo...
