Damping of Injection Oscillations
نویسنده
چکیده
The increasing dimensions and beam intensities of the new circular accelerators and colliders impose special demands on the performance of injection and transverse feedback systems. Injection errors blow up the emittance of a beam. The emittance increment with active feedback depends on the combination of injection error amplitude, tune spread and extra damping (above the needs for stability) by the feedback. A description of the transverse feedback system (TFS) for damping of injection oscillations is given. The TFS includes a subsystem for damping of transverse instabilities and a pulse subsystem for damping of injection errors with high damping rate. The optimization of the subsystem parameters is discussed, and the results obtained for damping rate of the beam are presented.

Transversal oscillation of coronal loops that are interpreted as signatures of magneto hydrodynamics (MHD) waves are observed frequently in active region corona loops. The amplitude of this oscillation has been found to be strongly attenuated. The damping of transverse oscillation may be produced by the dissipation mechanism and the wake of the traveling disturbance. The damping of transversal ...

A coronal loop can be oscillated in various directions. A basic type of coronal loop oscillation is called transverse oscillation that can be caused by different factors, such as nearby active regions and flares. The damping of transverse oscillation may be produced by the dissipation mechanism or the wake of the traveling disturbance. The aim of this paper is to estimate the damping time of tr...

In this paper, damping of interarea oscillations using simultaneous coordination of static Var compensator (SVC) and power system stabilizer (PSS) is considered. To be effective in damping of oscillations, the best-input signal of power oscillation damper (POD) associated with SVC is selected using Hankel singular values (HSVs), and right-hand plane zeros (RHP-zeros). The 4-machine-2 area...
