I Final Focus Systems for Linear Colliders

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...

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...

A Novel Final Focus Design for Future Linear Colliders

The length, complexity and cost of present Final Focus designs for linear colliders grow very fast with the beam energy. Because of the tight tolerances and delicate tuning required there are serious questions as to whether they could ever reach design performance. In the following paper, a novel final focus system is presented and compared with the one proposed for NLC \cite{ZDR}. This new des...
