In this paper, we present an electric-thermal drill with a novel design of a melting head that was developed within the EnEx-RANGE project. The design combines a short melting head with a large surface area of parabolic shape. It was succesfully tested in the laboratory as well as on Alpine glaciers (Langenferner and Mittelbergferner) and at the Ross Ice Shelf in Antarctica. In all these different environments, a high melting speed per specific power of typically 8.8 cm3 w−1 h−1 is achieved that is close to the ideal maximum bound of ~10.5–11.8 cm3 w−1 h−1 when neglecting all heat losses. It has also been demonstrated that the melting probe can be operated with typical equipment of small-scale field camps including a small power generator.

用于冰川研究的高效融化探针

在本文中，我们介绍了一种在 EnEx-RANGE 项目中开发的具有新型熔化头设计的电热钻。该设计结合了短熔头和抛物线形状的大表面积。它在实验室以及高山冰川（Langenferner 和 Mittelbergferner）和南极洲的罗斯冰架上成功进行了测试。在所有这些不同的环境中，每单位功率的熔化速度通常为 8.8 cm3w-1H-1达到接近理想的最大界限 ~10.5–11.8 cm3w-1H-1当忽略所有热损失时。还证明了熔化探针可以与小型野营营地的典型设备（包括小型发电机）一起操作。
