欧洲核子研究组织（CERN）的大型强子对撞机（LHC）目前提供在质心（c.m.）能量为13 TeV。大型强子对撞机的设计始于30多年前，其物理计划将持续到2030年代的下半年。全球未来圆形对撞机（FCC）研究正在为后LHC项目做准备。FCC的研究重点是在一个新的类似100公里的隧道中设计一个100 TeV的强子对撞机（FCC-hh）。它还包括设计一个高光度的电子-正电子对撞机（FCCee）作为潜在的中间步骤，以及轻子-强子对撞机选项（FCC-he）。FCC研究的范围包括加速器、技术、基础设施、探测器、物理学、全球数据服务的概念、国际治理模式和实施方案。在FCC的核心技术中，图16-T偶极磁体，基于Nb-3 S（n）超导体，用于FCC-hh强子对撞机，以及用于FCC-ee轻子对撞机的高效超导射频系统。根据FCC的概念，北京高能物理研究所（IHEP）已经启动了中国e（+）e（-）Higgs工厂（CEPC）的平行设计研究，该工厂将由高能强子对撞机（SPPC）接替。目前，隧道周长为54公里，强子对撞机为厘米。70 TeV左右的能量。在简要介绍了LHC之后，本文报告了FCC研究的动机和现状，一些主要的设计挑战和研发主题，以及新兴的全球合作。
The Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN) presently provides proton-proton collisions at a center-of-mass (c.m.) energy of 13 TeV. The LHC design was started more than 30 years ago, and its physics program will extend through the second half of the 2030's. The global Future Circular Collider (FCC) study is now preparing for a post-LHC project. The FCC study focuses on the design of a 100-TeV hadron collider (FCC-hh) in a new similar to 100 km tunnel. It also includes the design of a high-luminosity electron-positron collider (FCCee) as a potential intermediate step, and a lepton-hadron collider option (FCC-he). The scope of the FCC study comprises accelerators, technology, infrastructure, detectors, physics, concepts for worldwide data services, international governance models, and implementation scenarios. Among the FCC core technologies figure 16-T dipole magnets, based on Nb-3 S (n) superconductor, for the FCC-hh hadron collider, and a highly-efficient superconducting radiofrequency system for the FCC-ee lepton collider. Following the FCC concept, the Institute of High Energy Physics (IHEP) in Beijing has initiated a parallel design study for an e (+) e (-) Higgs factory in China (CEPC), which is to be succeeded by a high-energy hadron collider (SPPC). At present a tunnel circumference of 54 km and a hadron collider c.m. energy of about 70 TeV are being considered. After a brief look at the LHC, this article reports the motivation and the present status of the FCC study, some of the primary design challenges and R&D subjects, as well as the emerging global collaboration.
