0004078ManningThis grant provides partial support to the Department of Earth & Space Sciences at UCLA for the acquisition of a state-of-the-art electron microprobe (EMP) equipped with five wavelength dispersive spectrometers and capabilities for the analysis of light elements (Z 9) and digital imaging of backscattered electrons. The new EMP will replace the current but antiquated (vintage 1984) Camebax EMP that is beginning to show signs of instrument failure (i.e. stage positioning drift, frequent computer control crashes and failing vacuum pumps). This state-of-the-art instrument will serve a large number of faculty including Craig Manning, Paul Warren, Frank Kyte, John Wasson, Mary Reid, Mark Harrison, Kevin McKeegan, Anne Yin and Alan Rubin for studies ranging from Himalayan tectonics to subduction zone metasomatism to chemical processes in the early solar system. Support for this acquisition is shared roughly equally between NSF, NASA and UCLA.***

0004078Manning该拨款为加州大学洛杉矶分校地球空间科学系提供部分支持，用于购买最先进的电子微探针（EMP），该探针配备有五个波长色散光谱仪，并具有分析轻元素（Z 9）和背散射电子数字成像的能力。 新的EMP将取代当前但过时的（1984年的老式）Camebax EMP，后者开始显示出仪器故障的迹象（即载物台定位漂移、频繁的计算机控制崩溃和真空泵故障）。 这种最先进的仪器将服务于大量的教师，包括克雷格曼宁，保罗沃伦，弗兰克凯特，约翰沃森，玛丽里德，马克哈里森，凯文麦基根，安妮尹和艾伦鲁宾的研究范围从喜马拉雅构造俯冲带交代在早期太阳系的化学过程。 NSF、NASA和UCLA大致平均分担了对此次收购的支持。
