Intense Corkscrewing and Wobbling Elliptic Beams in a Piecewise Uniform Magnetic Focusing Field
نویسندگان
چکیده
It is shown that intense corkscrewing and periodic wobbling elliptic beam equilibria exist in piecewise uniform magnetic fields. The envelope stability analysis reveals that the corkscrewing elliptic beams in a uniform magnetic field are stable, whereas the periodic wobbling elliptic beams are stable in certain regions in the parameter space. These results are useful not only in beam matching, but also in producing large-aspect-ratio sheet beams for high energy accelerators such as the next linear collider as well as for use in high-power rf sources such as sheet-beam klystrons.

The envelope oscillations of a cold-fluid corkscrewing elliptic beam in a uniformfocusing magnetic field are studied. In particular, by linearizing the generalized beam envelope equations, the eigenmodes of small-amplitude envelope oscillations are calculated for a cold-fluid corkscrewing elliptic beam oscillating about its equilibrium. All of the eigenmodes are shown to be stable. PACS: 29.27....

In this study, nonlocal nonlinear instability and the vibration of a double carbon nanotube (CNT) system have been investigated. The Visco-Pasternak model is used to simulate the elastic medium between nanotubes, on which the effect of the spring, shear and damping of the elastic medium is considered. Both of the CNTs convey a viscose fluid and a uniform longitudinal magnetic field is applied t...
