Specialized upper-division laboratories in fields of contemporary interest are an important component of a vital physics curriculum. This Occidental College Physics Department project is developing two such laboratories in the areas of solid state and plasma physics. These laboratories, to be taken concurrently with lecture courses already offered by the department, complement the lecture presentation of particular topics as well as broaden the scope of these courses by introducing students to experimental techniques of the type used in current scientific research.In the solid state laboratory, students investigate important condensed matter phenomena such as resistivity, the polarity of charge carriers, the crystalline bandgap, electron-hole recombination, impurity doping of a semiconductor, and semiconductor statistics. The experiments familiarize students with cryogenic techniques and introduce state-of-the-art instrumentation such as a lock-in amplifier, scanning monochromator and digitizing oscilloscope. Many of the experiments involve computer-controlled data acquisition and sophisticated data analysis schemes (e.g., boxcar correlator).The plasma laboratory, the first of its kind at a small liberal arts college, is based on two custom made plasma-containment machines: the double plasma and the pure electron plasma devices. Through seven experiments, students explore single particle drifts, plasma wave dispersion and damping, plasma stability, and transport. Additionally, students become acquainted with vacuum technology and computer- controlled data acquisition/analysis techniques.NSF grant funds are being matched with funds from non-federal sources.

专业的高级实验室， 当代利益是一个重要的组成部分， 物理课程 本西方大学物理系 该项目正在开发两个这样的实验室， 固态和等离子体物理学。这些实验室， 同时， 部门，补充特别的讲座介绍 主题，并扩大这些课程的范围， 向学生介绍实验技术， 在当前的科学研究中使用。在固态下， 实验室，学生研究重要的凝聚态物质 诸如电阻率，电荷载流子的极性， 晶体带隙，电子空穴复合，杂质 半导体的掺杂和半导体统计学。 的 实验使学生熟悉低温技术， 引入最先进仪器，例如锁定 放大器、扫描单色仪和数字化示波器。 许多实验涉及计算机控制的数据 采集和复杂的数据分析方案（例如， boxcar相关器）。等离子体实验室，第一个同类实验室 在一个小的文科学院，是基于两个定制的 等离子体密封机：双等离子体和纯等离子体 电子等离子体装置通过七个实验，学生 探索单粒子漂移、等离子体波色散和 阻尼、等离子体稳定性和传输。此外，本发明还 学生熟悉真空技术和计算机， 受控数据采集/分析技术 与非联邦资金来源相匹配。
