Analytical Treatment of the Emittance Growth in the Main Linacs of Future Linear Colliders
نویسنده
چکیده
In this paper the single and multibunch emittance growths in the main linac of a linear collider are analytically treated in analogy to the Brownian motion of a molecule, and the analytical formulae for the emittance growth due to accelerating structure misalignment errors are obtained by solving Langevin equation. The same set of formulae is derived also by solving directly Fokker-Planck equation. Comparisons with numerical simulation results are made and the agreement is quite well.

Emittance and Trajectory Control in the Main Linacs of the Nlc
The main linacs of the next generation of linear colliders need to accelerate the particle beams to energies of up to 750 GeV while maintaining very small emittances. This paper describes the main mechanisms of static emittance growth in the main linacs of the Next Linear Collider (NLC). We present detailed simulations of the trajectory and emittance control algorithms that are foreseen for the...
متن کاملIon Effects in Future Circular and Linear Accelerators
In this paper, we discuss ion effects relevant to future storage rings and linear colliders. We ®rst review the conventional ion effects observed in present storage rings and then discuss how these effects will differ in the next generation of rings and linacs. These future accelerators operate in a new regime because of the high current long bunch trains and the very small transverse beam emit...
متن کاملOperation and Expected Performance of the NLC
‘The main linacs for the proposed Next Linear Collider (NLC) provide acceleration of up to 500 GeV per beam. The linacs operate in a regime where unavoidable imperfections and even natural ground motion cause significant emittance dilutions. In order to achieve the NLC luminosity goals, small emittance beams must be transported with an emittance growth of less than SLAC-PUB-7354 November 1996 O...
