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.

这个项目使得凝聚态物理学的发展 与所提供的课程结合使用的实验 从大二到大四 物理课程 该设备使用方便，操作灵活， 它支持各种固态物理的能力 实验，而且相当免费的维护。 固态 物理实验室使用两种温度控制系统： (1)自制实验用液氮恒温器 在77 K和室温之间，和（2）闭合循环 液氦制冷机，用于10 K和 室温 第二个是为这个项目而购买的， 允许进行低温实验，而不需要 购买、储存和转移液氦。 一 实验室计算机系统用于实验控制， 数据采集和数据分析在一些更 先进的实验，以及其他现代 使用仪器来对实验进行全面的检测。
