Some Observations on Bunch Lengthening
The phenomenon of current dependent bunch lengthening discovered at AC0 and ADONE about seven years ago can be used as an engineering diagnostic tool to examine how the longitudinal electromagnetic field of a beam couples to its surroundings. 1 The importance of isolating such coupling factors is that they may give rise to damaging instabilities. Another practical reason for studying the effect...
متن کاملBunch Lengthening Thresholds on the Daresbury Srs
The behaviour of single bunch beams in the SRS have been studied in some detail [1, 2]. This behaviour is largely dependent upon the basic impedances of the vacuum chamber experienced by the electron beam. This paper presents recent results which provide further information on these impedances and their effects. In particular, the data clearly demonstrates microwave instability thresholds and p...
متن کاملLongitudinal Bunch Lengthening Compensation in a High Charge Rf Photoinjector
In high charge RF photoinjectors for wakefield two beam acceleration studies, due to the strong longitudinal space charge, bunch lengthening between the photocathode and photoinjector exit is a critical issue. We present beam dynamics studies of bunch lengthening in an RF photoinjector for a high charge electron beam and describe methods to compensate the bunch lengthening to various degrees. I...
متن کاملAdditional Bunch Lengthening Results on the Aco Srfel
We present additional low current bunch lengthening data from the ACO-SRFEL project which further verfity the stochastic heating model. We present supplemental results of the bunch lengthening experiment in addition to those already discussed by the LURE/Stanford Free Electron Laser Group at Orsay, France in these proceedings [1]. These results are signal strength as a function of operating fre...
متن کاملBunch Lengthening Calculations for the Slc Damping Rings’
The problem of bunch lengthening in electron storage rings has been treated by many people, and there have been many experiments. In the typical experiment, the theory is used to determine the impedance of the ring. What has been lacking thus far, however, is a calculation of bunch lengthening that uses a carefully calculated ring impedance (or wakefield). In this paper we begin by finding the ...
