Electron spectroscopy for chemical analysis (ESCA) (aka x-ray photoelectron spectroscopy) is one of the most developed and versatile of the modern surface analysis techniques and has unique capabilities beyond those of any instrumentation currently found in undergraduate science and engineering laboratories. This technique is routinely used for the characterization of surface and subsurface layers and interfaces of a wide variety of materials, providing insight into their elemental composition, oxidation states, structure, and bonding. Although ESCA is a well-established technique, used extensively in both academia and industry, few undergraduate programs teach the theory associated with it, and no institution has incorporated its use into undergraduate course-related laboratories. In the past, all commercially available instruments were not only expensive ($500,000 and up), but were very temperamental and required extensive training to operate. With the recent advent of lower cost ($200,000 range), user-friendly, instruments designed for on-line inspection, the feasibility of ESCA's becoming a routine teaching tool has been established. The potential for utilization of ESCA by students (both chemists and engineers) is great. Knowledge of this technique and its capabilities gives students an awareness of the types of analyses that are currently being performed, not only in industrial and academic research laboratories, but also on the floor of manufacturing facilities. This project provides one ESCA spectrometer for use in the science and engineering curriculum. ESCA experiments are incorporated into six chemistry, one physics, and two or more engineering laboratories. *

用于化学分析的电子能谱（ESCA）（又名X射线光电子能谱）是现代表面分析技术中最先进和最通用的技术之一，具有超越目前在本科科学和工程实验室中发现的任何仪器的独特能力。 该技术通常用于表征各种材料的表面和次表面层以及界面，从而深入了解其元素组成、氧化态、结构和键合。 尽管ESCA是一种成熟的技术，在学术界和工业界广泛使用，但很少有本科课程教授与之相关的理论，也没有机构将其使用纳入本科课程相关的实验室。 在过去，所有商业上可用的仪器不仅昂贵（50万美元以上），而且非常喜怒无常，需要广泛的培训才能操作。 随着最近出现的低成本（20万美元范围），用户友好，仪器设计的在线检查，ESCA的可行性成为一个例行的教学工具已经建立。 学生（化学家和工程师）利用ESCA的潜力很大。 这种技术及其能力的知识使学生了解目前正在进行的分析类型，不仅在工业和学术研究实验室，而且在制造设施的地板上。 本计画提供一台ESCA能谱仪供理工科课程使用。 ESCA实验被纳入六个化学实验室，一个物理实验室和两个或更多的工程实验室。 *
