Beam-beam Phenomena in Linear Colliders
نویسنده
چکیده
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 phenomena involving the quantum eld theory. The synchrotron radiation in the beam-beam eld, called beamstrahlung, becomes extremely energetic. The strong eld can even create electronpositron pairs from the beamstrahlung photons. In the present lecture note both the classical and quantum phenomena are described.

A Low Emittance, Flat-beam Electron Source for Linear Colliders
We present a method to generate a flat (large horizontal to vertical emittance ratio) electron beam suitable for Linear Colliders. The concept is based on a round-beam rf-laser gun with finite solenoid field at the cathode together with a special beam optics adapter. Computer simulations of this new type of beam source show that the beam quality required for a Linear Collider may be obtainable ...
متن کاملA High Intensity Linear Ee Collider Facility at Low Energy
The huge luminosity increase compared to existing ring colliders is expected by using linear collider concepts. The luminosities of past and existing ee ring colliders have been steadily increased mainly by increasing the beam currents and collision frequencies. The design luminosities of various ee ring colliders are shown in Fig. 1 as function of the beam energy. A main limitation comes from ...
متن کاملDisruption Effects from the Collision of Quasi-Flat Beams*
Absiract The disruption effects from the collision of round beams and flat beams in linear colliders have been studied in the past, and has by now been well understood. In practice, however, in the current SLC running condition and in several designs of the next generation linear colliders, the quasi-flat beam geometries are expected. Namely, the beam aspect ratio R z us/or > 1, but not infinit...
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...
