Abstract

It has been found for the first time in experiments with an electron beam that space-charge waves can be generated not only in pairs. A single slow wave, a single fast wave, or combinations of the two waves with different amplitude and polarity relations have been produced experimentally in a space-charge dominated beam. Analytical solutions derived from one-dimensional fluid equations show the amplitude and polarity of each space-charge wave as a function of the initial perturbation parameters. The theory provides the correct interpretation of the experimental observations.

Nonlinear Behavior of Localized Space-Charge Waves in Space-Charge Dominated Electron Beams

Journal Article Zou, Y; Wang, J; Suk, H; ... - Physical Review Letters

We present experimental observations of the abnormal growth of localized nonlinear space-charge waves in space-charge dominated electron beams passing through a resistive channel. The energy width of the space-charge waves is measured on both ends of the channel. Previous experiments had shown that, for small initial perturbations, the energy width of the slow waves increases, while the energy width of the fast waves decreases, in agreement with linear theory. We report that in the nonlinear regime (large initial perturbations), the energy width of the fast wave increases, which is unexpected, and, to the best of our knowledge, no theory existsmore »« less

Experimental studies of longitudinal dynamics of space-charge dominated beams

Journal Article Wang, J; Reiser, M - AIP Conference Proceedings

We review the experimental results of our research on longitudinal dynamics of space-charge dominated beams. The topics include three recent experiments. In the longitudinal compression experiments, we investigated the longitudinal density profiles of bunched beams. In the space-charge wave experiments, we studied the behavior of localized perturbations as fast and slow waves in beams. The resistive-wall instability experiments were designed to measure the growth of perturbations in a dissipative environment, and the damages to beam quality. On-going and future work is also discussed. {copyright} {ital 1996 American Institute of Physics.}

Time-dependent imaging of space-charge dominated electron beams

Journal Article Tian, K; Kishek, R; O'Shea, P; ... - Physics of Plasmas

When considered as non-neutral plasmas, space-charge dominated charged particle beams have significantly smaller Debye lengths than their beam sizes. Therefore, collective effects due to space-charge forces are very important to the beam dynamics. As an example, density perturbations generated in a space-charge dominated charge particle beam will stimulate longitudinally space-charge waves. To study the modification of transverse beam distributions by longitudinal beam dynamics, experimental studies of low-energy electron beams, with and without longitudinal density perturbations, have been undertaken at the University of Maryland's electron ring and the Long Solenoid Experiment (LSE). We have taken time-resolved beam images on these machinesmore »« less

Experimental studies of longitudinal dynamics of space-charge dominated electron beams

Conference Wang, D.

A comprehensive experimental program was carried out at Univ. of Maryland Beam Transport facility to study the longitudinal beam physics of space-charge dominated bunches. This investigation included the behavior of (a) bunches with parabolic line charge profile, (b) bunches with rectangular line charge profile, and (c) local perturbations (slow and fast waves) in rectangular bunches. The major experimental results are presented in this paper.

Determination of the geometry factor for longitudinal perturbations in space-charge dominated beams

Journal Article Wang, J; Suk, H; Wang, D; ... - Physical Review Letters; (United States)

We present the results of an experimental investigation of the parametric dependence of the geometry factor [ital g] associated with line-charge perturbations in space-charge dominated beams. The experiment consists of a novel method of launching localized space-charge waves and measuring simultaneously the wave velocity and the radius [ital a] of an electron beam propagating through a periodic focusing channel with pipe radius [ital b]. We find that the [ital g] factor obeys the relation [ital g]=2 ln([ital b]/[ital a]). This result is supported by theoretical analysis, and is also in agreement with previous theoretical work.
