Ultra high vacuum (UHV) techniques are becoming standard for the study of materials and surface problems. This project will develop a high quality UHV facility so that Colgate can introduce training in these important techniques and experience with materials science problems into their upper level laboratory program. They intend to incorporate a carefully supervised training module into the experimental methods course, provide experimental exercises to support the Solid State Physics course, and use the system as a major station in the advanced laboratory program. In addition, there is a wide range of research problems in materials and surface science that are manageable for talented undergraduates to accomplish as independent projects. The basis for the project is a UHV system with a stainless steel test chamber that can be configured to accept a variety of experiments. Additional features to be incorporated are: (1) an ion sputter gun to get surfaces atomically clean, (2) a residual gas analyzer to support the training program in UHV techniques, and to do experiments in desorption of gasses from surfaces, (3) a means to prepare high quality thin films by evaporation, and (4) a reflection high energy electron diffraction system to investigate the structure of prepared films in situ, and make possible electron diffraction experiments.

超高真空 (UHV) 技术正在成为材料和表面问题研究的标准。 该项目将开发高质量的特高压设施，以便高露洁能够将这些重要技术的培训和材料科学问题的经验引入其上层实验室计划。 他们打算将精心监督的培训模块纳入实验方法课程，提供实验练习来支持固体物理课程，并将该系统用作高级实验室计划的主要站点。 此外，材料和表面科学领域存在广泛的研究问题，这些问题可以由有才华的本科生作为独立项目来完成。 该项目的基础是带有不锈钢测试室的特高压系统，可配置为接受各种实验。 要纳入的其他功能包括：(1) 离子溅射枪，使表面达到原子级清洁，(2) 残留气体分析仪，支持 UHV 技术培训计划，并进行表面气体解吸实验，(3)一种通过蒸发制备高质量薄膜的方法，以及（4）反射高能电子衍射系统，用于原位研究所制备薄膜的结构，并使电子衍射实验成为可能。
