Acquisition of Closed Cycle Helium Liquefaction System

纽约州立大学物理系 斯托尼布鲁克的约克将购买一个过程系统 国际1410型氦液化系统， 更换（和升级）20岁恶化现有的 一个. 该设备将用于几个正在进行的 材料研究项目，主要工作在高 铜氧化物和富勒烯的温度超导性， 约瑟夫森结与电子学，分数量子霍尔 宏观量子现象和单电子 隧道 使用闭合循环氦液化 该系统将大大降低研究资助的成本 由NSF和其他联邦和州机构提供， 保护有限的自然资源氦气。

The Department of Physics at the State University of New York at Stony Brook will purchase a Process Systems International model 1410 helium liquefaction system to replace (and upgrade) the 20years old deteriorated existing one. The equipment will be used for several ongoing materials research projects, primarily work on high temperature superconductivity in cuprates and fullerence, Josephson junctions and electronics, fractional quantum Hall effect, macroscopic quantum phenomena, and single-electron tunneling. Use of a closed cycle helium liquefaction system will significantly reduce the cost of research funded by NSF and other federal and state agencies and contribute to conservation of a limited natural resource-helium gas.
