Wake-field and fast head-tail instability caused by an electron cloud.
In positron and proton storage rings, electrons produced by photoemission, ionization, and secondary emission accumulate in the vacuum chamber during multibunch operation with close spacing. A positron or proton bunch passing through this "electron cloud" experiences a force similar to a short-range wake field. This effective wake field can cause a transverse-mode-coupling instability, if the e...
متن کاملResistive-wall Instability Experiment in Space-charge Dominated Electron Beams
The resistive-wall instability of charged particle beams has been experimentally studied in space-charge dominated electron beams. The beam energy is in the range of 3 to 8.5 keV, the beam current is between 25 mA and 62 mA. In the experiment, electron beams produced from a thermionic cathode are passed through a 0.96 m long glass tube coated with a resistive material, and localized space-charg...
متن کاملProof of Cloud Instability with Respect to the Formation of Several Horizontal Space Charge Layers
The origin of the multiple horizontal charge layers observed in the trailing stratiform region of mesoscale convective systems is explained for the first time on the basis of energy considerations and stability calculations. The latter indicate the presence of a cloud-instability with respect to formation of horizontal polarization layers and associated space charge layers. The author's polariz...
متن کاملMonopole-charge instability∗
For monopoles with non-vanishing Higgs potential it is shown that with respect to “BrandNeri-Coleman type” variations (a) the stability problem reduces to that of a pure gauge theory on the two-sphere (b) each topological sector admits one, and only one, stable monopole charge, and (c) each unstable monopole admits 2 ∑ q<0 (2|q| − 1) negative modes, where the sum goes over all negative eigenval...
متن کاملSimulation of Head-Tail Instability Caused by Electron Cloud in the Positron Ring at PEP-II∗
The head-tail instability caused by an electron cloud in positron storage rings is studied numerically using a simple model. In the model, the positron beam is longitudinally divided into many slices that have a fixed transverse size. The centroid of each slice evolves dynamically according to the interaction with a two-dimensional electron cloud at a given azimuthal location in the ring and a ...
