Upgrading of high-pressure experimental petrology laboratory at University of New Mexico

EAR-0446524 NSF仪器和设施元素的DraperSupport将用于升级新墨西哥大学的高压设施。现有的多座压力机将进行翻新，以纠正一些小问题，并将进一步精简其操作程序。现有的较小压力机将改装成第二个多座压力机，从俄勒冈大学购买的活塞-气缸架将安装新的部件，使其投入使用。这项工作完成后，该实验室达到研究地球、月球和火星深处岩石学过程所需压力的能力将翻一番。新的活塞-圆柱体还将使我们能够获得与中到深地壳到上地幔过程有关的较低压力，适用于陆地和火星研究。该实验室支持两名首席研究人员和几名研究生，并计划培养一名新的博士后科学家。这些升级将产生一个坚固的设施，在研究行星内部方面具有较长的预期生产性工作寿命。

EAR-0446524DraperSupport from NSF's Instruments and Facilities element will be used to upgrade the high-pressure facility at the University of New Mexico. The existing multi-anvil press will be refurbished to correct some minor problems, and additional streamlining of its operational procedures will take place. An existing, smaller press will be converted to a second multi-anvil, and a piston-cylinder frame acquired from the University of Oregon will be fitted with new components to bring it into service. At the completion of this work, the lab's capacity to reach pressures appropriate for studying petrological processes in the deep interiors of the Earth, Moon, and Mars will be doubled. The new piston-cylinder will also allow us access to lower pressures relevant to mid- to deep-crustal to upper-mantle processes applicable to both terrestrial and martian studies. The lab supports two principal investigators and several graduate students, with plans for a new postdoctoral scientist as well. These upgrades will yield a robust facility with a long projected lifespan of productive work in studying planetary interiors.
