Acquisition of A New Electron Microprobe at UCLA

这项拨款为加州大学洛杉矶分校地球与空间科学系提供了部分支持，用于购置最先进的电子微探针（EMP），该探针配备了五个波长色散光谱仪，具有分析轻元素（z9）和背散射电子数字成像的能力。新的EMP将取代目前过时的（1984年的老式）camamebax EMP，该EMP开始显示仪器故障的迹象（即级定位漂移，频繁的计算机控制崩溃和真空泵故障）。这台最先进的仪器将为包括Craig Manning， Paul Warren, Frank Kyte, John Wasson, Mary Reid, Mark Harrison, Kevin McKeegan， Anne Yin和Alan Rubin在内的大量教师提供服务，研究范围从喜马拉雅构造到俯冲带的变质作用到早期太阳系的化学过程。NSF、NASA和UCLA对此次收购的支持大致平分

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.***
