MRI: Acquisition of a Shared ESEM Facility for the Colorado School of Mines

科罗拉多矿业学院将建立一个环境扫描电子显微镜(ESEM)实验室，以满足CSM校园日益增长的研究和教育需求。拟建的环境扫描电子研究实验室将是一个共用设施，校园内的大多数部门都会广泛参与。该设施将加强材料科学系最近成立的电子显微镜中心，为丰富本科生和研究生教育提供焦点。此外，它还将作为当地工业的资源设施。建议购买一台配有温控样品台(加热和冷却)的环境扫描电子显微镜，以及用于元素测绘的能量色散光谱(EDS)。这种配置被选为以合理的成本最大化多功能性的最佳配置。环境扫描电子显微镜保留了传统扫描电子显微镜的性能优势，但消除了高真空(10-6托)的限制。环境扫描电子显微镜得名于它能够通过一定范围的压力(10-6)操纵样品环境。20托)、温度(-20-1000摄氏度)和气体组成。这项研究提供的灵活性将使其在CSM园区得到广泛使用。

The Colorado School of Mines will to establish an Environmental Scanning Electron Microscope (ESEM) laboratory to meet the growing research and education needs of the CSM campus. The proposed ESEM laboratory will be a shared-use facility, with extensive participation from the majority of departments across campus. The facility will augment the recently established electron microscopy center in the materials science department, providing a focal point to enrich undergraduate and graduate education. In addition, it will serve as a resource facility for local industry. The proposed to acquire an ESEM equipped with temperature controlled sample stages (both heated and cooled), as well as energy dispersive spectroscopy (EDS) for elemental mapping. This configuration was chosen as the optimum with respect to maximizing versatility at a reasonable cost. An ESEM retains the performance advantages of a conventional SEM, but removes the high vacuum (10-6 torr) constraints. The ESEM derives its name from its ability to manipulate the sample environment through a range of pressure (10-6. 20 torr), temperature (-20 - 1000 degrees C), and gas composition. The flexibility offered by this research will allow it to find widespread use on the CSM campus.
