尽管铀和钍在地球内部的分布成像的潜在的和独特的好处,以前提出的实验技术用于确定传入的地球中微子的方向是不适用于实际的成像,由于在中微子的轨道重建的高错误识别。通过实验研究和蒙特-卡罗模拟,我们证实了用6Li中微子探测器进行中微子跟踪识别的可能性。对于可能的成像应用,我们还探讨了产生巨大的岩浆库和地幔深部结构的地质中微子图像的可行性。我们预计并计划将这些新设计的探测器应用于地球内部的射线照相成像,核反应堆的监测,以及跟踪中微子的天体物理来源。
Despite the latent and unique benefits of imaging uranium and thorium's distribution in the earth's interior, previously proposed experimental techniques used to identify the incoming geo-neutrino's direction are not applicable to practical imaging due to the high miss-identification in a neutrino's track reconstruction. After performing experimental studies and Monte-Carlo simulations, we confirmed that a significant improvement is possible in neutrino tracking identification with a 6Li-loaded neutrino detector. For possible imaging applications, we also explore the feasibility of producing geo-neutrinographic images of gigantic magmatic reservoirs and deep structure in the mantle. We anticipate and plan to apply these newly designed detectors to radiographic imaging of the Earth's interior, monitoring of nuclear reactors, and tracking astrophysical sources of neutrinos.
