摘要

由于低重复率(5 ~ 200 Hz)和高加速梯度(22 ~ 150 MeV/m)，未来的线性对撞机在许多方面都有很大的不同。对于高光度，光束尺寸必须压缩在极小的相互作用点(IP)区域内。我们简要地描述了IP上的新现象，即光束strastralung过程，e+e -对和微型射流的产生。我们还报告了与能量传播，光束strahlung，束列结构，光束偏振和探测器和物理学背景相关的机器含义。

Machine implications for detectors and physics

Future linear colliders are very different at many aspects because of low repetition rate (5∼200 Hz) and high accelerating gradient (22∼150 MeV/m). For high luminosity, the beam sizes must be squeezed in extremely small region at interaction point (IP). We briefly describe new phenomena at the IP, i.e. beamstrahlung process, creations of e+e− pairs and minijets. We also report machine implications related to the energy spread, beamstrahlung, bunch-train structure, beam polarizations and backgrounds for detectors and physics.
