The EDAX Component of a Scanning Electron Microscope

扫描电子显微镜的EDAX组件一种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，而物理和生物专业的学生则较少使用。整个四年的本科课程都受到这种仪器的影响。为了激发学生们对科学的兴趣，并向他们展示什么是可能的，以激发他们的想象力，学生们在每门入门课程，动态地球和海洋学中至少两次使用仪器。二年级和三年级学生必修的地球科学课程，特别是沉积学、矿物学、岩石学、构造学和古生物学的实验经验，由于使用了这种仪器而得到了很大的修改。除了宏观世界之外，微观世界现在也可以进行化学表征了。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。通过我们与凯克地质联合会的其他11个地质系的积极参与，校外的学生也受到了这一改进的影响。* * * 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
