在粒子物理研究领域,陶粲能区具有独特的性质、丰富的前沿物理课题和重大的科学发现潜力,是该领域重点关注的能区之一。为了使我国在该研究领域引领世界,中国科学家提出新一代超高亮度正负电子对撞机超级陶粲装置(英文全称Super Tau-Charm Facility, 简称STCF)。


中国超级陶粲装置项目是继北京正负电子对撞机(BEPCII)之后,中国未来可能的对撞机项目之一,设计亮度为0.5*1035cm-2·s-1,运行在质心能量2‒7 GeV能区,比目前正在运行的北京正负电子对撞机能量覆盖范围更大,亮度提高50倍以上,其上的探测器性能更加优良,将极大提升粲物理和强子谱学的研究能力,在陶轻子物理研究上取得开创性新成果,从而精确检验粒子物理标准模型和寻找新物理。该装置将为探索宇宙中正反物质的不对称性(CP破缺)、深入研究强子内部结构及非微扰强相互作用本质、寻找奇异物质和超越标准模型的新物理现象等前沿重大课题提供关键平台。


STCF加速器和探测器的建造将挑战众多国际最前沿的关键技术。该攻关项目于2022年启动,预计2025年完成关键技术攻关。受中国高能物理学会委托,中国科学技术大学牵头组织并联合国内外的研究单位开展该项目概念性设计和前期的预研工作。2015‒2020年分别由中国科学技术大学(2015 2020)、中国科学院大学(2018)、法国直线加速器实验室(2018)、俄罗斯科学院新西伯利亚核物理研究所(BINP)(2019)、承办了超级陶粲装置(STCF)的国际联合研讨会,来自中国、俄罗斯、瑞典、韩国、德国、意大利、波兰、美国和以色列等数百名国内外专家参与了相关会议。下一届国际研讨会将于2024114日至18日在中国科学技术大学举行。


由中外82家单位、400余位专家参与撰写的STCF conceptual design report (Volume 1): Physics & detector已经于Frontiers of Physics发表并上线【Front. Phys. 19(1), 14701 (2024)】。装置相关细节亦可以参考http://www.wuli.ac.cn/cn/article/doi/10.7693/wl20200803https://arxiv.org/abs/2303.15790
