Feasibility Study for a Dark Matter Search co-located with the IceCube Detector in the Antarctic Ice

本提案旨在为2010/2011年夏季在冰立方/DeepCore阵列中心附近的两个冰立方深冰孔底部部署两个8.5 kg NaI（Tl）探测器提供支持。由于即将到来的南方夏季将是冰立方MREFC项目的最后一个季节，威斯康星大学通过NSF的RAPID资助机制提交了这项提案，以便能够利用最后2500米深的冰洞和通信电缆，这些电缆将已经部署在冰立方数字光学模块串上。拟议中的NaI（Tl）探测器将被安装在最后两根冰立方细绳的底部，并使用细绳的“特殊装置”电源和通信电线将数据发送到表面。

This proposal seeks support for deployment of two 8.5 kg NaI(Tl) detectors at the bottom of two IceCube deep ice holes which will be drilled near the center of IceCube/DeepCore array during the austral summer of 2010/2011. Since the forthcoming austral summer season will be the last of the IceCube MREFC project, the University of Wisconsin submitted this proposal through the NSF's RAPID funding mechanism to be able to take advantage of the last 2500-m deep ice holes and communication cables that will already be deployed for the IceCube string of Digital Optical Modules. The proposed NaI(Tl) detectors will be attached to the bottom of these last two IceCube strings and use the string's "special device" power and communication wires to send data to the surface.
