Cryogen Support for PVAMU extreme Conditions lab

材料研究部的这一奖项为草原景观农工大学(PVAMU)采购物资提供支持，以运营具有集成隧道二极管振荡器(TDO)能力的10毫升开尔文稀释冰箱系统。TDO测量是一种测量样品电阻率的非接触式方法。冰箱和TDO将提供广泛探测无机和有机材料以及重费米子系统的电子和磁性所需的分辨率。它将进一步允许更广泛的电子性质。此外，稀释冰箱扩展了标准技术的能力，如直流电气传输、磁化、比热和压力，允许它们在极端温度环境中进行。稀释制冷机系统与隧道二极管振荡器相结合，使科学家能够扩展以前研究的材料的相边界，并牢固地建立新系统的相边界。该系统非常适合我们来自北卡罗来纳农工大学、洛斯阿拉莫斯国家实验室和希腊的合作者目前正在研制的重费米子系统。它还将帮助PVAMU的教授继续现有的初级物理学家体验计划，该计划允许高三和大四学生在少数族裔服务机构获得宝贵的实验室技能。这一计划将有助于增加未被充分代表的科学家的数量。

This award from the Division of Materials Research provides support Prairie View A&M University (PVAMU) for acquisition of supplies to operate a 10 milliKelvin Dilution Refrigerator System with integrated Tunnel Diode Oscillator (TDO) capabilities. TDO measurements are a contactless means of measuring sample resistivity. The Refrigerator and TDO will provide the resolution needed for extensive probing of the electronic and magnetic properties of inorganic and organic materials and heavy fermion systems. It will further permit extensive of the electronic properties. In addition, the dilution refrigerator extends the capabilities of standard techniques such as DC electrical transport, magnetization, specific heat and pressure by allowing them to be conducted in an extreme temperature environment. The dilution refrigerator system coupled with the tunnel diode oscillator allows the scientists to extend the phase boundaries of previously studied materials and firmly establish the phase boundaries of new systems. This system is ideal for heavy fermion systems being currently grown by our collaborators from North Carolina A&T University, Los Alamos National Lab and Greece. It will also help the professors at PVAMU to continue existing Junior Physicist Experience Program which allows high school juniors and seniors to gain valuable laboratory skills at a minority serving institution. This program will help increase the number of underrepresented scientists.
