没有地下实验室的地下物理学：溶液开采盐穴中的大型探测器
Underground physics without underground labs: large detectors in solution-mined salt caverns
摘要：
当前的一些物理学课题，包括长基线中微子物理学、质子衰变搜索和超新星中微子搜索，都希望有一天能在屏蔽的地下场所建造巨大的（50千吨到百万吨）粒子探测器。在今天的实践中，这需要昂贵的挖掘和稳定矿井中的大房间。在本文中，我们建议利用溶采盐所产生的洞穴。挑战在于，这些洞穴必须充满加压流体，并且不允许人类进入。我们勾勒出一些可能的方法，在盐穴中安装熟悉的探测器技术，在这些限制。所讨论的一些探测器也适用于深海实验，对此作了简要讨论。这些草图看起来具有挑战性，但可行，似乎对探测器的能力没有什么重大影响。该方案为未来探测器大型项目节省大量成本提供了途径。
英文摘要：
A number of current physics topics, including long-baseline neutrino physics, proton decay searches, and supernova neutrino searches, hope to someday construct huge (50 kiloton to megaton) particle detectors in shielded, underground sites. With today's practices, this requires the costly excavation and stabilization of large rooms in mines. In this paper, we propose utilizing the caverns created by the solution mining of salt. The challenge is that such caverns must be filled with pressurized fluid and do not admit human access. We sketch some possible methods of installing familiar detector technologies in a salt cavern under these constraints. Some of the detectors discussed are also suitable for deep-sea experiments, discussed briefly. These sketches appear challenging but feasible, and appear to force few major compromises on detector capabilities. This scheme offers avenues for enormous cost savings on future detector megaprojects.
