Abstract

The length, complexity, and cost of the present final focus designs for linear colliders grow very quickly with the beam energy. In this Letter, a novel final focus system is presented and compared with the one proposed for the Next Linear Collider (NLC Zeroth-Order Design Report, edited by T. O. Raubenheimer, SLAC Report No. 474, 1996). This new design has fewer optical elements and is much shorter, nonetheless achieving better chromatic properties. Moreover, the new system is more suitable for operation over a larger energy range.

摘要

目前直线对撞机最终聚焦设计的长度、复杂度和成本会随着束流能量迅速增加。在本信函中，提出了一种新型最终聚焦系统，并将其与为下一代直线对撞机（由T. O. 劳本海默编辑的《NLC零阶设计报告》，SLAC报告第474号，1996年）所提议的系统进行比较。这种新设计的光学元件更少，长度也短得多，但仍具有更好的色散特性。此外，新系统更适合在更大的能量范围内运行。
