Improving and Modernizing Instrumentation for the Advanced Laboratory

高级实验序列服务于具有多种最终目标的学生；研究生院，工业就业和教学。因此，在这一序列中使用了各种各样的实验和教学模式。在现代仪器快速发展的背景下，为了确保这个序列的质量，我们必须增加让学生接触测量的实验：(i)产生需要详细分析的大量数据，（ii）是现代技术的例子，（iii）不仅仅需要与计算机进行敷衍的交互。购买射频设备和数字示波器将使脉冲核磁共振和第二声实验能够产生大量，高质量的数据。为现有的高真空薄膜蒸发器购买光纤元件和某些附件，将有助于开展实验，说明现代光纤技术、薄膜制造和薄膜特性以及真空技术的各个方面。购买个人电脑将允许一些实验的自动化，傅里叶变换技术的引入，并增加学生对数据分析设施的访问。购买逻辑分析仪可以对实验-计算机接口要求进行严格检查。

The advanced laboratory sequence serves students having a variety of final goals; graduate school, industrial employment and teaching. Accordingly, a wide variety of experiments and teaching modes are used in this sequence. To ensure the quality of this sequence in a context of rapid developments in modern instrumentation, we must add experiments that expose the students to measurements which: (i) produce large volumes of data requiring detailed analysis, (ii) are examples of modern technologies, and (iii) require more than a perfunctory interaction with computers. Purchase of rf equipment and digital oscilloscopes will enable pulsed NMR and second-sound experiments to produce large-volume, high-quality data. Purchase of fiber optics components and certain accessories for an existing high-vacuum thin film evaporator will enable the development of experiments illustrating aspects of the modern technologies of fiber optics, thin film fabrication and thin-film properties, and vacuum techniques. Purchase of PC's will permit the automation of some experiments, the introduction of Fourier transform techniques, and increase student access to data analysis facilities. Purchase of logic analyzers permits a critical examination of experiment-computer interfacing requirements.
