继2012年在大型强子对撞机上发现希格斯玻色子之后，国际高能界正在考虑和研究新的大型对撞机，以详细探索希格斯玻色子，并探索标准模型之外的新物理。在中国，提出了一个两级圆形对撞机项目，CEPC-SPPC，目前正在研究中。第一阶段，CEPC（圆形电子正电子科利尔，所谓的希格斯工厂）的重点是希格斯物理，和第二阶段，SPPC（超级质子质子对撞机）将是一个能量前沿对撞机和发现机器超越LHC。这两个对撞机将共用一个周长为100公里的隧道，CEPC的质心目标为250 GeV，SPPC第一阶段为75 TeV，SPPC最终目标为125-150 TeV。本文介绍了SPPC的设计思想和一些关键的加速器物理问题和技术问题的研究结果，包括亮度优化、束流准直、束-束效应、纵向束流动力学、强场磁体和束屏。
Following the discovery of the Higgs boson at the LHC in 2012, new large colliders are being considered and studied by the international high-energy community to explore the Higgs boson in details and to probe new physics beyond the Standard Model. In China, a two-stage circular collider project, CEPC-SPPC was proposed and is under study. The first stage, CEPC (Circular Electron Positron Collier, a so-called Higgs factory) is focused on the Higgs physics, and the second stage, SPPC (Super Proton-Proton Collider) will be an energy frontier collider and a discovery machine beyond the LHC. The two colliders will share a same tunnel of 100 km in circumference, with a goal of 250 GeV in center-of-mass for CEPC and 75 TeV for SPPC Phase-I and 125–150 TeV for the SPPC ultimate goal. This article presents the design concept of the SPPC and some study results about the key accelerator physics problems and technical issues, which include luminosity optimization, beam collimation, beam-beam effects, longitudinal beam dynamics, high-field magnets and beam screen.
