An X-ray transparent experimental triaxial rock deformation apparatus, here named `Mjölnir', enables investigations of brittle-style rock deformation and failure, as well as coupled thermal, chemical and mechanical processes relevant to a range of Earth subsurface environments. Designed to operate with cylindrical samples up to 3.2 mm outside-diameter and up to 10 mm length, Mjölnir can attain up to 50 MPa confining pressure and in excess of 600 MPa axial load. The addition of heaters extends the experimental range to temperatures up to 140°C. Deployment of Mjolnir on synchrotron beamlines indicates that full 3D datasets may be acquired in a few seconds to a few minutes, meaning full 4D investigations of deformation processes can be undertaken. Mjölnir is constructed from readily available materials and components and complete technical drawings are included in the supporting information.
一种X射线透明的实验性三轴岩石变形装置，这里命名为“雷神锤”，能够研究脆性岩石变形与破坏，以及与一系列地球地下环境相关的热、化学和力学耦合过程。“雷神锤”设计用于外径达3.2毫米、长度达10毫米的圆柱形样品，可实现高达50兆帕的围压和超过600兆帕的轴向载荷。添加加热器可将实验温度范围扩展至高达140°C。将“雷神锤”部署在同步加速器光束线上表明，可在几秒到几分钟内获取完整的三维数据集，这意味着可以对变形过程进行完整的四维研究。“雷神锤”由易于获取的材料和部件制成，完整的技术图纸包含在补充信息中。
