MRI- Consortium: Acquisition of Cryogen-free Cryocooler-based Physical Property Measurement System to Support Transformative Device and Materials Research in the Rio Grande Valley

1126410martirosyan这项拨款申请的目的是获得一个尖端的商业多功能仪器，基于无低温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德克萨斯州南部里约热内卢格兰德山谷地区的应用物理教育计划。该设备将安装在德克萨斯大学布朗斯维尔分校，并将用作共享表征设施。该仪器设计用于测量不同温度（1.9 - 1000 K），磁场（高达9 T）和环境（从大气压到高真空）下的各种材料性能，包括磁性，输运和热学。该系统不含低温剂，不需要昂贵的液态低温剂。PPMS的吸引人的特点是一个制冷机，以实现低温。PPMS EverCool-II是一种高度自动化的仪器。它可以在用户安装样品并配置测量后执行无人值守的测量。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大用户提供最先进的测量系统，从而将里约热内卢格兰德山谷的先进材料研究和教育项目提升到全球竞争水平。

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.
