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

9350822 Mertzman 扫描电子显微镜的 EDAX 组件 用于扫描电子显微镜的能量色散 X 射线微分析系统 (EDAX) 正在被地球科学系的学生使用，物理和生物学系的学生也有少量使用。 在四年的本科生经历中，课程受到这种仪器的影响。 为了让学生对科学感到兴奋，并向他们展示激发想象力的可能性，学生们在每门入门课程、动态地球和海洋学中至少使用两次仪器。大二和大三必修的地球科学课程，特别是沉积学、矿物学、岩石学、结构和古生物学的实验室经验，正在根据使用这些仪器的情况进行相当大的修改。 除了宏观世界之外，现在还可以对微观世界进行化学表征。 本科生研究机会的经验广度、深度和数量都在大幅增加。通过我们与凯克地质学联盟的其他十一个地质系的积极参与，来自我们机构之外的学生也受到了这一改进的影响。 ***y
