The EDAX Component of a Scanning Electron Microscope

9350822 Mertzman是扫描电子显微镜的能谱分析组件，这是一种用于扫描电子显微镜的能量色散X射线显微分析系统，地球科学系的学生正在使用该系统，物理和生物专业的学生使用的程度较小。在整个四年的本科课程中，课程都受到了这种工具的影响。为了让学生对科学感到兴奋，并向他们展示激发他们想象力的可能性，学生们在每门导论课程--地球动力学和海洋学--中至少使用了两次这种仪器。二年级和三年级的地球科学必修课，特别是沉积学、矿物学、岩石学、构造学和古生物学的实验室经验，由于获得了这种仪器，正在进行相当大的修改。现在，除了宏观世界外，微观世界还可以进行化学表征。经验的广度、深度和本科生研究机会的绝对数量正在大幅增加。来自我们学院以外的学生也受到了这一进步的影响，我们与凯克地质联盟中的其他11个地质系积极参与。*y

9350822 Mertzman The EDAX Component of a Scanning Electron Microscope An energy dispersive x-ray microanalytical system (EDAX) for a scanning electron microscope is being used by the students in the geosciences department and to a lesser extent by students in physics and biology. The curriculum is being impacted by this instrumentation throughout the four year undergraduate experience. To get the students excited about science and to show them what is possible in order to fire their imaginations, students are making use of the instrumentation at least twice in each of the introductory courses, dynamic earth and oceanography. Sophomore and junior required geosciences courses, particularly the lab experiences in sedimentology, mineralogy, petrology, structure, and paleontology are being modified considerably in light of access to this instrumentation. The microworld is now accessible to chemical characterization in addition to the macroworld. The breadth of experience, the depth, and the sheer number of undergraduate research opportunities is being substantially increased. Students from outside our institution are being impacted by this improvement, too, through our very active participation with eleven other geology departments in the Keck Geology Consortium. ***y
