A Solid State Physics Laboratory for Intermediate and Advanced Majors

这个项目允许凝聚态物理实验的开发与大学二年级到大学四年级物理课程的课程结合使用。该设备易于使用，能够灵活地支持各种固态物理实验，并且相当免维护。固体物理实验室采用了两种温度控制系统：(1)自制的液氮低温恒温器，用于77K至室温的实验；(2)闭式循环液氦制冷机，用于10K至室温的实验。第二个是为这个项目而获得的，它允许进行低温实验，而不需要购买、储存和转移液氦。在一些更高级的实验中，使用实验室计算机系统进行实验控制、数据采集和数据分析，并使用附加的现代仪器来完全测量实验。

This project allows the development of condensed matter physics experiments to be used in conjunction with the courses offered in the sophomore through senior years of the undergraduate physics curriculum. The equipment is easy to use, flexible in its ability to support a wide variety of solid state physics experiments, and fairly free of maintenance. The solid state physics laboratory utilizes two temperature control systems: (1) a home-made liquid nitrogen cryostat for experiments between 77 K and room temperature, and (2) a closed cycle liquid helium refrigerator for experiments between 10 K and room temperature. The second, acquired for this project, allows for low temperature experiments without the need for purchasing, storing, and transferring liquid helium. A laboratory computer system is used for experimental control, data acquisition, and data analysis in some of the more advanced experiments, and additional pieces of modern instrumentation are used to instrument fully the experiments.
