U.S.-Japan Joint Seminar: Innovative Measurement Techniques in Cryogenics

9910937 Van Science该奖项支持美国科学家参加2000年12月4日至7日在佛罗里达州塔拉哈西举行的美日低温创新管理技术研讨会。联合组织者是佛罗里达州立大学的Steven Van Sciver教授和日本筑波高能加速器研究组织(KEK)的Tomiyoshi Haruyama教授。该主题涵盖了超导磁体和低温系统中涉及的许多测量问题。将讨论三个主要主题领域：1)低温下压力、温度、液位和流量测量设备的最新发展；2)超导磁体和空间低温系统等技术系统中的测量技术；以及3)潜在感兴趣的创新测量技术。具体主题包括流量测量技术、脉冲管制冷、粒子图像测速、低温压力传感器、声发射/摩擦、低温机器、低温传热学、空间低温测量、高分辨率温度和压力、He II中第二声的探测和高雷诺数He II的产生。研讨会的目的是鼓励研究人员之间更密切的合作，开发新的设备和更有目标的应用，可以利用这些新技术。他们还希望为年轻的科学家和工程师提供该领域最先进的总体看法。近年来，这一领域取得了相当大的进展。其中一些进展是由超导磁体系统和基于空间的技术等应用推动的。其他主要应用还包括制冷技术的发展，特别是小型冷冻机。研讨会组织者做出了特别努力，让年轻的研究人员既作为参与者又作为观察员。与日本专家在这一领域交换想法和数据将使美国参与者能够推进他们自己的工作，并将为未来的合作项目奠定基础。研讨会会议记录的传播计划包括在《低温》杂志上发表文章。

9910937Van SciverThis award supports the participation of American scientists in a U.S.-Japan seminar on Innovative Management Techniques in Cryogenics, to be held in Tallahassee, Florida, from December 4-7, 2000. The co-organizers are Professors Steven Van Sciver at Florida State University and Professor Tomiyoshi Haruyama at the High Energy Accelerator Research Organization (KEK) in Tsukuba, Japan. The topic encompasses many of the measurement issues involved in superconducting magnet and cryogenic systems. Three main topic areas will be discussed: 1) recent developments in measurement devices for pressure, temperature, level and flow at low temperature; 2) measurement techniques in technical systems such as superconducting magnets and space cryogenic systems; and 3) innovative measurement techniques of potential interest. Specific topics include flow metering techniques, pulse tube refrigeration, particle image velocimetry, low temperature pressure transducer, acoustic emission/friction, low temperature machines, low temperature heat transfer, space cryogenics measurements, high resolution temperature and pressure, detection of second sound in He II and generating high Reynolds number He II. The goal of the seminar is to encourage closer cooperation between the researchers developing new devices and the more goal-oriented applications, which could utilize these new techniques. They also hope to provide an overall view of the state-of-the-art in the field for young scientists and engineers. There has been considerable progress in this field over recent years. Some of this progress has been driven by applications such as superconducting magnet systems and space based technology. Other major applications are in development of refrigeration, particularly small-scale cryocollers. Seminar organizers have made a special effort to involve younger researchers as both participants and observers. The exchange of ideas and data with Japanese experts in this field will enable U.S. participants to advance their own work, and will set the stage for future collaborative projects. Dissemination plans for the seminar proceedings include publication in the journal "Cryogenics."
