摘要

我们报告了下一代线性对撞机(NLC)阻尼环复合体(DRC)的设计进展。DRC的目的是为NLC直线加速器提供120 Hz,低发射度的电子和正电子束列车。它由2个1.98 GeV主阻尼环、1个正电子预阻尼环、2对束长和能量压缩系统以及相互连接的输送管线组成。2个主阻尼环在3列95串中存储高达0.8安培,并具有归一化提取的光束发射/spl gamma//spl isin//sub x/=3 /spl mu/m-rad和/spl gamma//spl isin//sub y/=0.03 /spl mu/m-rad。给出了初步的光学设计、性能指标和公差。关键子系统包括:1)714 MHz射频系统,2)60 ns上升时间注入/提取脉冲踢动磁体,3)44 m摆动磁体系统,4)电弧和摆动真空系统,5)辐射管理系统,6)光束诊断仪器,7)下游机器保护专用系统和8)基于反馈的稳定系统。

The Next Linear Collider damping ring complex
We report progress on the design of the Next Linear Collider (NLC) damping rings complex (DRC). The purpose of the DRC is to provide 120 Hz, low emittance electron and positron bunch trains to the NLC linacs. It consists of two 1.98 GeV main damping rings, one positron pre-damping ring, two pairs of bunch length and energy compressor systems and interconnecting transport lines. The 2 main damping rings store up to 0.8 amp in 3 trains of 95 bunches each and have normalized extracted beam emittances /spl gamma//spl isin//sub x/=3 /spl mu/m-rad and /spl gamma//spl isin//sub y/=0.03 /spl mu/m-rad. The preliminary optical design, performance specifications and tolerances are given. Key subsystems include: 1) the 714 MHz RF system, 2) the 60 ns risetime injection/extraction pulsed kicker magnets, 3) the 44 m wiggler magnet system, 4) the arc and wiggler vacuum system, 5) the radiation management system, 6) the beam diagnostic instrumentation, 7) special systems used for downstream machine protection and 8) feedback-based stabilization systems.
