大型强子对撞机将于2005年投入使用，它将为粒子物理学提供第一个进入1TeV以上能量前沿的实验室工具。为了实现这一目标，质子必须被加速并以7TeV的速度存储，碰撞的光度达到前所未有的10/sup 34/cm/sup-2/S/sup-1/。用传统的NbTi技术冷却到氦的兰达点以下，获得了8.3特斯拉的导磁场。需要对现有大型正负电子对撞机(LEP)隧道周围的基础设施进行相当大的改造，以容纳LHC机器和探测器。该项目正在按计划推进，包括低温和磁体在内的大部分主要硬件系统正在建设中，本文简要介绍了项目的现状，并对未来的前景进行了展望。
The Large Hadron Collider (LHC), due to be commissioned in 2005, will provide particle physics with the first laboratory tool to access the energy frontier above 1 TeV, In order to achieve this, protons must be accelerated and stored at 7 TeV, colliding with an unprecedented luminosity of 10/sup 34/ cm/sup -2/ s/sup -1/. The 8.3 Tesla guide field is obtained using conventional NbTi technology cooled to below the lambda point of helium. Considerable modification of the infrastructure around the existing Large Electron Positron collider (LEP) tunnel is needed to house the LHC machine and detectors. The project is advancing according to schedule with most of the major hardware systems including cryogenics and magnets under construction, A brief status report is given and future prospects are discussed.
