Developing opportunities for LAr discovery science at the Boulby Underground Laboratory

这项提议将探索和发展机会，通过使用液态Ar时间投影室和尖端硅光传感器和电荷像素读出技术，在直接暗物质探测、中微子物理和新型仪器开发领域为英国和博尔比地下实验室带来新的世界领先的国际实验。拟议的工作将使国际实验界了解未来可能开展的任何大规模液氮科学方案的雄心和要求，并通过与布尔比地下实验室工作人员的密切合作，确保实验室的发展能够提供这些机会。该提案将探讨利用博尔比现有实验室空间开发用于开发新仪器技术的实验试验台设施的可行性和设计要求；确定在博尔比建造低温恒温器以容纳新的暗物质/中微子物理实验的要求；并对以下两方面进行必要的研究并形成文件：(I)制定概念设计，以便在未来十年内在博尔比实验室的未来扩建内选址具有世界领先的科学发现潜力的此类实验，以及(Ii)向国际社会宣传英国和博尔比是未来在这些领域进行大规模科学投资的可信地点，并吸引国际用户群到英国。

This proposal will explore and develop the opportunity to bring new world-leading, international experiments to the UK and to the Boulby Underground Laboratory in the areas of direct dark matter detection, neutrino physics, and novel instrumentation development through the use of liquid argon time projection chambers and cutting-edge silicon photosensor and charge pixel readout technologies. The proposed work will engage the international experimental communities to capture the ambitions and requirements for any future large-scale liquid argon science programme that could be pursued, and through close collaboration with staff at the Boulby Underground Laboratory ensure that the development of the Laboratory is directed to enable these opportunities. This proposal will explore the feasibility and design requirements to exploit both the existing laboratory space at Boulby to develop an experimental testbed facility for the development of new instrumentation technologies; determine the requirements for the construction of a cryostat at Boulby to host a new dark matter / neutrino physics experiment; and perform and document the necessary studies to both:(i) develop the concept designs for siting such an experiment with world-leading scientific discovery potential in the next decade within a future expansion of the Boulby laboratory, and (ii) promote the UK and Boulby to the international community as a credible site for future large-scale scientific investment in these areas and to attract an international user base to the UK.
