Instrumentation for Plasma Physics and Vacuum Science-Based Upper Division Experimental Physics Course

物理系正在为物理专业的学生开设一门高年级实验物理课程，使每个物理专业的学生都有机会使用最新的仪器在基础质物理和真空科学领域进行实验。开设这样一门课程是对物理学士学位课程质量的重大改进。该仪器包括一个围绕325 1/s扩散泵建立的真空系统。电子设备（Lockin放大器，Boxcar积分器和计算机接口（GPIB））和静电探针（Langmuir探针，网格能量分析仪）允许基本的等离子体参数测量，包括等离子体密度和静电势，电子和离子温度和分布函数。并进行了离子声波、离子束和混沌动力学实验。该仪器还包括一个数字存储示波器，它与IBM PC/AT兼容计算机集成，用于数据采集和分析。通信软件提供访问大学的VAX计算机进行离线数据分析。该大学将提供等额的资助。

The physics department is creating an upper division experimental physics course for physics majors that will give each physics major an opportunity to do experiments with up-to-date instrumentation in the area of basic plasm physics and vacuum science. The creation of such a course constitutes a major improvement in the quality of the Physics Bachelor's Degree program. The instrumentation includes a vacuum system built around a 325 1/s diffusion pump. Electronic equipment (Lockin Amplifier, Boxcar Integrator & Computer Interface (GPIB) and electrostatic probes (Langmuir Probes, Gridded Energy Analyzer) permit fundamental plasma parameter measurements, including plasma density and electrostatic potential, electron and ion temperature and distribution functions. Ion acoustic wave, ion beam, and chaotic dynamics experiments are being performed as well. The instrumentation also includes a digital storage oscilliscope which is integrated with an IBM PC/AT compatible computer for data acquisition and analysis. Communications Software provides access to the University's VAX computers for off line data analysis. The University is matching the award with an equal amount of funds.
