Electron-cloud Effects in High-luminosity Colliders
نویسنده
چکیده
Electron-cloud instabilities are expected to be important in most high-luminosity double-ring colliders. In this report, I describe a few parameter regimes and some critical parameter dependences of this type of instability, and illustrate these with simulation results for the PEP-II and KEK B factories, the LHC, the VLHC, and DAPHNE. In addition, I study the possibility and the potential impact of an electron cloud in the interaction region.

متن کاملHigh Luminosity Muon Collider Design
Muon Colliders have unique technical and physics advantages and disadvantages when compared with both hadron and electron machines. They should be regarded as complementary. Parameters are given of 4 TeV high luminosity μμcollider, and of a 0.5 TeV lower luminosity demonstration machine. We discuss the various systems in such muon colliders.
متن کاملUltimate luminosities and energies of photon colliders ∗
A photon collider luminosity and its energy are determined by the parameters of an electron-electron linear collider (energy, power, beam emittances) and collision effects. The main collision effect is the coherent e+e− pair creation. At low energies (2E< 0.5–1 TeV) this process is suppressed due to repulsion of electron beams. In this region Lγγ(z > 0.65) ≥ 1035cm−2s−1 is possible (1033 − 1034...

Using the laser backscattering method at future TeV linear colliders one can obtain γγ and γe colliding beams (photon colliders) with the energy and luminosity comparable to that in ee collisions. Now this option is included to conceptual designs of linear colliders. This paper (talk at the conference on nonlinear optics) is a short introduction to this field with an emphasis on required lasers...
متن کاملHigh Energy Photon Colliders. *
Using the laser backscattering method at future linear colliders one can obtain γγ and γe colliding beams (photon colliders) with energy and luminosity comparable to that in ee collisions. This option has been included in the pre-conceptual designs of linear colliders and in work on a Technical Design Report which is in progress. The physics motivation for photon colliders is quite clear. The p...
