Abstract

The Next Linear Collider (NLC) injector system is designed to produce low emittance, 10 GeV electron and positron beams at 120 hertz for injection into the NLC main linacs. Each beam consists of a train of 95 bunches spaced by 2.8 ns; each bunch has a population of 1.15/spl times/10/sup 10/ particles. At injection into the main linacs, the horizontal and vertical emittances are specified to be /spl gamma//spl isin//sub x/=3/spl times/10/sup 16/ m-rad and /spl gamma//spl isin//sub y/=3/spl times/10/sup -8/ m-rad and the bunch length is 100 /spl mu/m. Electron polarization of greater than 80% is required. Electron and positron beams are generated in separate accelerator complexes each of which contain the source, damping ring systems, L-band, S-band, and X-band linacs, bunch length compressors, and collimation regions. The need for low technical risk, reliable injector subsystems is a major consideration in the design effort. This paper presents an overview of the NLC injector systems.

NLC注入系统

下一代直线对撞机(NLC)注入系统设计用于产生低发射度，10 GeV的120赫兹电子和正电子束注入NLC主直线加速器。每个光束由95束组成，间隔2.8纳秒;每一束有1.15/ sp1倍/10/sup 10/粒子的人口。在注入主直线时，规定水平和垂直发射强度为/spl gamma//spl isin//sub x/=3/spl倍/10/sup 16/ m-rad和/spl gamma//spl isin//sub y/=3/spl倍/10/sup -8/ m-rad，束长为100 /spl mu/m。要求电子极化率大于80%。电子和正电子束在单独的加速器复合体中产生，其中每个复合体包含源、阻尼环系统、l波段、s波段和x波段直线加速器、束长压缩器和准直区域。对低技术风险、可靠的喷油器子系统的需求是设计工作中的主要考虑因素。本文介绍了NLC喷油器系统的概况。
