欧洲核研究组织完成了首个HGCAL原型,即高精度硅探测器,用于LHC2030年升级,研究稀有粒子碰撞。 CERN finished the first HGCAL prototype, a high-precision silicon detector for the LHC’s 2030 upgrade, to study rare particle collisions.

CERN的科学家们完成了高粒度量热器（HGCAL）的首个原型盒，这是CMS实验在高光度LHC2030年启动前的重大升级。 Scientists at CERN have completed the first prototype cassette for the High-Granularity Calorimeter (HGCAL), a major upgrade for the CMS experiment ahead of the High-Luminosity LHC’s 2030 startup. 在法国建造的网形部件是有史以来最大的以硅为基础的探测器的一部分,其目的是每秒处理多达4 000万次碰撞,其中140至200次同时发生。 The wedge-shaped component, built in France, is part of the largest silicon-based detector ever planned, designed to handle up to 40 million collisions per second with 140–200 occurring simultaneously. HGCAL横跨47层,拥有300多万个频道,将提供前所未有的5D探测位置、能量和时间,精确到第二次改进粒子识别和触发的万亿分之一。 Featuring over 3 million channels across 47 layers, the HGCAL will provide unprecedented 5D detection—spatial position, energy, and timing precision down to trillionths of a second—improving particle identification and triggering. 电磁部分使用来自6个全球中心的硅模块,而Fermilab则建造时空部分。 The electromagnetic section uses silicon modules from six global centers, while Fermilab builds the hadronic section. 探测器将承受强烈辐射,并能够更准确地研究稀有粒子过程。 The detector will withstand intense radiation and enable more precise study of rare particle processes.
