摘要

为了达到Next线性对撞机的设计亮度,主直线加速器必须将束束从10 GeV加速到500 GeV,同时保持垂直归一化发射率为0.05 mm.mrad。我们描述了一组仿真研究,使用程序说谎者,比较几种算法转向主线;从发射度保持、收敛速度和对BNS相位轮廓的灵敏度等方面对两种算法进行了比较。还研究了ATL机构在转向过程中的作用。

Simulation studies of main linac steering in the Next Linear Collider
In order to achieve the design luminosity of the Next Linear Collider, the main linac must accelerate trains of bunches from 10 GeV to 500 GeV while preserving vertical normalized emittances on the order of 0.05 mm.mrad. We describe a set of simulation studies, performed using the program LIAR, comparing several algorithms for steering the main linac; the algorithms are compared on the basis of emittance preservation, convergence speed, and sensitivity to BNS phase profile. The effects of an ATL mechanism during the steering procedure are also studied.
