New Student Projects using Digital Image Analysis and Low Temperatures

高级物理实验室正在开发一系列令人兴奋的、半研究水平的新可能性。这项拨款提供了两个新领域的工作设备——数字图像采集和处理，以及使用密闭循环冰箱的物质的温度依赖特性。数字成像设备将使分形聚集体、游泳生物动力学、振荡化学反应中的混沌行为和快速光谱学等项目成为可能。使用闭合循环制冷机将探索的物质的一些性质是高Tc超导体的温度依赖电导率，磁化率的量子振荡，固体的温度依赖光学性质，以及通过磁相变的固体比热。

A new series of exciting, semi-research-level possibilities in the Advanced Physics Laboratory is being developed. Equipment for work in two new areas -- digital image acquisition and processing, and temperature-dependent properties of matter using closed cycle refrigerators is provided by this grant. The digital imaging equipment will make possible projects on fractal aggregates, dynamics of swimming organisms, chaotic behavior in oscillating chemical reactions, and rapid optical spectroscopy. Some properties of matter that will be explored using the close cycle refrigerators are temperature-dependent conductivity in high Tc Superconductors, quantum oscillations in magnetic susceptibility, temperature-dependent optical properties of solids, and specific heats of solids through magnetic phase transitions.
