LHCb Upgrade 2 bridging Oct 2023 - March 2024

LHCb探测器的第二次重大升级，LHCb升级II，将通过提供独特的探测能力最大限度地提高高亮度LHC的发现潜力。该实验旨在利用LHC碰撞中重口味（美丽和魅力）粒子的高生产率，通过循环过程精确搜索标准模型之外的物理。LHCb升级II建立在LHCb实验的现有基础设施上，升级了所有子探测器系统和新的元件，这些元件将通过使用精确的定时信息来解决来自同一束中不同碰撞的粒子。数据将以比目前可能的更高的速度记录，从而产生一个广泛而令人兴奋的物理计划。该申请是为LHCb升级II英国工作的研发阶段和随后的施工前阶段提供6个月的过渡资金。它提供了关键的连续性努力，这对英国保持在国际项目中的领导地位至关重要。英国的努力集中在具体的战略技术上，这些技术将使LHCb升级II的物理目标得以实现，同时也将产生广泛的影响。

The second major upgrade of the LHCb detector, LHCb Upgrade II, will maximise the discovery potential of the High Luminosity LHC by providing unique detection capability. The experiment is designed to exploit the high production rate of heavy flavoured (beauty and charm) particles in LHC collisions, enabling precision searches for physics beyond the Standard Model through loop processes. LHCb Upgrade II builds on the existing infrastructure of the LHCb experiment, with upgrades to all subdetector systems and new elements that will provide capability to resolve particles from different collisions in the same bunch crossing through the use of precision timing information. Data will be recorded at much higher rates than currently possible, leading to a broad and exciting physics programme. This application is for 6 months bridging funding between an R&D phase and a subsequent preconstruction phase of UK work on LHCb Upgrade II. It provides crucial continuity of effort, that is essential for the UK to maintain leadership in the international project. UK effort is focussed on specific, strategic technologies that will enable the physics goals of LHCb Upgrade II to be achieved while also achieving broad impact.
