Introducing State-of-the-Art Measurment Techniques into a Junior Modern Physics Laboratory

9452430 Croft这个项目将通过引入最先进的实验和数据分析技术来丰富我们大三的现代物理实验室。提议者是两名核实验学家和一名固态x射线光谱学家，他们致力于为这个本科生实验室注入现代研究方法的兴奋和力量，同时保持实验室作为教学实验室的作用。拟议的实验是从主要研究人员的专门知识中得出的。具体来说，其中一个丰富内容涉及将真正现代的粒子/核物理技术引入关于μ子寿命和宇宙射线方向依赖性的实验中。第二部分包括两部分介绍现代x射线光谱学方法。学生将首先利用先进的高分辨x射线探测系统，透过萤光辐射探索核及原子能能级方案。第二部分介绍了x射线吸收光谱（XAS）的数据分析和实验方法。对于实际的XAS测量，学生们将进行一次数据收集之旅，前往布鲁克海文国家同步加速器光源，这应该对他们产生特别高的激励影响。

9452430 Croft This project will enrich our junior year modern physics lab by introducing state-of-the-art experimental and data analysis techniques drawn directly from research. The proposers are two nuclear experimentalists and a solid state x-ray spectroscopist who are committed to the goal of infusing this undergraduate lab with a taste of the excitement and the power of modern research methods, while maintaining the role of the lab as a teaching lab. The proposed experiments are drawn from the expertise of the principal investigators. Specifically one of the enrichments involves introducing truly modern particle/nuclear physics techniques into an experiment on the muon lifetime and the directional dependence of cosmic rays. The second involves a two part introduction to modern x-ray spectroscopic methods. Students will first explore nuclear and atomic energy level schemes by fluorescent radiation with a sophisticated high resolution x-ray detection system. The second part involves the introduction to x-ray absorption spectroscopy (XAS) the data analysis and experimental methods. For the actual XAS measurements students will make a data collection trip to the Brookhaven National Synchrotron Light Source which should have a particularly high motivational impact on them.
