This proposal requests funds for an Environmental SEM (ESEM) for the Cornell Materials Science Center (MSC) Electron Microscope Facility. This instrument provides the special ability to observe a sample in gas atmospheres with typical pressure between about 1 to 20 Torr while the electron gun remains at high vacuum. This instrument will enable the Cornell materials community to perform research requiring the in-situ observation of samples during the experiments with environments having well controlled temperature and gas atmosphere. The research projects currently planned to use this SEM involve different materials such as ceramics, electronic materials, metals, and polymers. This instrument will be maintained by the MSC and made available to all interested users.

该提案要求为康奈尔材料科学中心(MSC)电子显微镜设施的环境扫描电子显微镜(ESEM)提供资金。该仪器提供了在典型压力约为1到20托的气体环境中观察样品的特殊能力，而电子枪保持在高真空状态。该仪器将使康奈尔大学材料界能够在温度和气体气氛得到很好控制的环境下进行研究，要求在实验期间对样品进行现场观察。目前计划使用这种扫描电子显微镜的研究项目涉及陶瓷、电子材料、金属和聚合物等不同材料。该仪器将由海管会维护，并向所有感兴趣的用户提供。
