The astroparticle physics community is searching for a practical way to improve the sensitivity to proton decay, which is one of the most exciting prediction of Grand Unified Theories and a fundamental corner stone for the understanding of matter anti-matter asymmetry observed in the Universe. The extension of existing and construction of new deep underground laboratories in Europe, Japan and USA is under investigation and challenged by enormous excavation and engineering costs. Here, we want to investigate whether the IceCube Neutrino Observatory with its GigaTon instrumented mass offers a valuable and cost effective alternative. We want to study the optimal geometry of an array of multi-PMTs modules to be deployed inside IceCube. IceCube will be operated as active veto providing an effective shielding equivalent to deep underground sites. The proposed feasibility study will utilize simulation and new computing technology. Moreover, a request for R&D on new photon detectors and multi-PMTs module is also contained in this proposal.

天体粒子物理界正在寻找一种实用的方法来提高对质子衰变的敏感性，这是大统一理论最令人兴奋的预测之一，也是理解在宇宙中观察到的物质反物质不对称的基本基石。欧洲、日本和美国的现有和新的深地下实验室的扩建正在调查中，并面临着巨大的开挖和工程成本的挑战。在这里，我们想要调查拥有十亿吨仪器质量的冰立方中微子天文台是否提供了一个有价值和成本效益的替代方案。我们想要研究部署在IceCube内的多PMTS模块阵列的最佳几何形状。冰立方将作为主动否决权运作，提供相当于深层地下地点的有效屏蔽。拟议的可行性研究将利用模拟和新的计算技术。此外，该提案还包含了对新的光子探测器和多PMT组件的研发请求。
