Coherent beam-beam interactions in electron-positron colliders.

We present the results of a new calculational technique that evaluates the beam-beam force due to an arbitrary cha.rge distribution. We find coherent instabilities that dominate at certain operating points and depend strongly on the degree of damping in the system. We conclude that while these resonances may play a significant role for colliders with low damping, with a careful choice of operat...

Coherent beam-beam tune shift of unsymmetrical beam-beam interactions with large beam-beam parameter.

Coherent beam-beam tune shift of unsymmetrical beam-beam interactions was studied experimentally and numerically in HERA, where the lepton beam has such a large beam-beam parameter (up to xi(y) = 0.272 ) that the single-particle motion is locally unstable at the origin (closed orbit). Unlike the symmetrical case of beam-beam interactions, the ratio of the coherent beam-beam tune shift and the b...

An electron–positron beam–plasma instability

Using a new technique to generate cold electron beams, an electron-beam positron-plasma experiment was performed in a previously unexplored range of energies. An electron beam, formed from a thermalized room-temperature electron plasma, is transmitted through a positron plasma stored in a quadrupole Penning trap geometry. The transit-time instability, which is excited by the beam, was previousl...

Beam-beam Phenomena in Linear Colliders

The beam-beam interaction in electron-positron linear colliders shows very di erent aspects from that in storage rings. The single-pass nature of the linear colliders allows drastic deformation of the bunch shape during one collision. Also, under the very strong electro-magnetic eld together with the high beam energy, phenomena which are not important in storage rings come into play, namely the...

Linac Coherent Light Source Electron Beam Collimation∗

This paper describes the design and simulation of the electron beam collimation system in the Linac Coherent Light Source (LCLS). Dark current is expected from the gun and some of the accelerating cavities. Particle tracking of the expected dark current through the entire LCLS linac, from gun through FEL undulator, is used to estimate final particle extent in the undulator as well as expected b...
