1126410MartirosyanThe objective of this grant application is to acquire a cutting-edge commercial multi-functional instrument Cryogen-free Cryocooler-based Physical Property Measurement System (PPMS EverCool-II, Quantum Design, USA) to support fundamental and interdisciplinary research projects and the applied physics education program in the Rio Grande Valley, South Texas region. The equipment will be installed at the University of Texas at Brownsville and will be used as a shared characterization facility. This instrument is designed to measure a variety of materials properties including magnetic, transport, and thermal under different temperatures (1.9 - 1000 K), magnetic fields (up to 9 T) and environments (from atmospheric pressure to high vacuum). The system is cryogen-free and no costly liquid cryogens are required. The attractive feature of the PPMS is a cryocooler to achieve cryogenic temperatures. The PPMS EverCool-II is a highly automated instrument. It can perform unattended measurements after the user has installed a sample and configured the measurement. This acquisition will enhance the existing research and educational infrastructure and will provide the state-of-the-art measurement system to a broad range of users in State of Texas, thereby elevating advanced materials research and educational programs in the Rio Grande Valley to a globally competitive level.

这项赠款申请的目标是获得一个尖端的商用多功能仪器，基于无制冷剂制冷机的物理性质测量系统(PPMS EverCool-II，Quantum Design，USA)，以支持基础和跨学科研究项目，以及南得克萨斯州里奥格兰德山谷的应用物理教育计划。这些设备将安装在德克萨斯大学布朗斯维尔分校，并将作为共享的表征设施使用。该仪器设计用于测量各种材料的性能，包括在不同温度(1.9-1000K)、磁场(高达9T)和环境(从大气压到高真空)下的磁、输运和热性能。该系统不含制冷剂，不需要昂贵的液体冷冻剂。PPMS的吸引人的特点是可以达到低温的低温冷却器。PPMS EverCool-II是一种高度自动化的仪器。在用户安装了样本并配置了测量后，它可以执行无人值守测量。此次收购将加强现有的研究和教育基础设施，并将为德克萨斯州的广泛用户提供最先进的测量系统，从而将格兰德河谷的先进材料研究和教育项目提升到具有全球竞争力的水平。
