Beam Dynamics in Linear Colliders*

چکیده
.In this paper, we discuss some basic beam dynamics issues related to obtaining and preserving the luminosity of a next generation linear collider. In Figure 1 you see a diagram illustrating the main subsystems of one-half of the collider. The beams are extracted from a damping ring and compressed in length by the first bunch compressor. They are then accelerated in a preaccelerator linac up to an energy appropriate for injection into a high gradient linac. In many designs this pre-accelera.tion is followed by another bunch compression to reach a short’ bunch. After acceleration in the linac, the bunches are finally focused transversely to a small spot.

BEAM DYNAMICS ISSUES in LINEAR COLLIDERS
The primary goal of present and future linear colliders is to maximize the integrated luminosity for the experimental program. Beam dynamics plays a central role in the maximization of integrated luminosity. It is the major issue in the production of small beam sizes and low experimental backgrounds and is also an important factor in the production of particle numbers, in the acceleration proce...
متن کاملBeam Dynamics Issues for Linear Colliders
In this paper we discuss various beam dynamics issues for linear col-liders. The emphasis is to explore beam dynamics effects which lead to an effective dilution of the emittance of the beam and thus to a loss of luminos-ity. These considerations lead to various tolerances which are evaluated for a particular parameter set.
متن کاملCrab-cavity Beam Dynamics Issues for an Lhc Upgrade
Modern colliders bring into collision a large number of bunches per pulse or per turn to achieve a high luminosity. The long-range beam-beam effects arising from parasitic encounters at such colliders are mitigated by introducing a crossing angle. Under these conditions, crab cavities can be used to restore effective head-on collisions and thereby to increase the geometric luminosity. Crab cavi...
متن کاملBeam-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...
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 کاملA 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 ...
