Beam delivery and final focus systems for multi-TeV advanced linear colliders

I Final Focus Systems for Linear Colliders

A Final Focus System for Flat-Beam Linear Colliders*

A final focus system is designed for a flat-beam linear collider with the parameters suggested by R. B. Palmer. A method of chromaticity correction which uses one family of sextupole is realized so as to correct both horizontal and vertical chromaticities simultaneously. A computer code has been written to find the solution, and a result with a momentum acceptance twice that of Palmer’s require...

Prospects for Multi-tev Two-beam Linear Colliders*

Recent work at CERN and SLAC has opened the possibility of the development of concrete designs for electron positron linear colliders that have a center of mass energy substantially above 1 TeV [1,2]. These designs are based on high gradient, normal conducting acceleration with the power provided by an auxiliary beam that is efficiently accelerated in a fully loaded, low frequency linac. This t...

A Conceptual Design of Final Focus Systems for Linear Colliders*

Linear colliders are a relatively recent development in the evolution of particle accelerators. This report discusses some of the approaches that have been considered for the design of Final Focus Systems to demagnify the beam exiting from a linac to the small size suitable for collisions at the interaction point. The system receiving the most attention is the one adopted for the SLAC Linear Co...

New Developments in Linear Colliders Final Focus Systems

The length, complexity and cost of the present Final Focus designs for linear colliders grows very quickly with the beam energy. In this paper, a novel final focus system is presented and compared with the one proposed for NLC [1]. This new design is simpler, shorter and cheaper, with comparable bandwidth, tolerances and tunability. Moreover, the length scales slower than linearly with energy a...
