9503743 Schwartz, Steven The award will allow the purchase of a replacement for a data acquisition and imaging system for a secondary ion mass spectrometry/Auger electron spectroscopy (SINS/Auger) instrument. This new data system will provide three dimensional imaging capability for the first time, so that spatial maps of elemental concentrations at the parts per million level can be produced. The data system will significantly enhance the machine sensitivity by storing large volumes of data for post-analysis. The new system will replace outdated counting-electronics modules and will incorporate specialized software for simultaneous SIMS/Auger data acquisition. The SIMS/Auger unit at Queens College is one of the most prolific SIMS instruments employed for materials research. Approximately 100 publications have utilized data from this instrument since 1985. These publications address a wide range of materials issues, including segregation and ordering in polymer blends, interdiffusion and metallic contacts in compound semiconductor devices, characterization of crystal growth, and fundamentals of ion-solid interactions. The machine is currently in round-the-clock use, in support of several research contracts and projects, and involving faculty from several universities, as well as researchers in industry.

小行星9503743 该合同将允许为二次离子质谱/俄歇电子能谱仪（AES/Auger）购买数据采集和成像系统的替代品。 这一新的数据系统将首次提供三维成像能力，从而可以生成百万分之一水平的元素浓度空间图。 该数据系统将通过存储大量数据以供后期分析来显著提高机器的灵敏度。 新系统将取代过时的计数电子模块，并将纳入同步西姆斯/Auger数据采集的专用软件。 皇后学院的西姆斯/Auger装置是用于材料研究的最多产的西姆斯仪器之一。 自1985年以来，约有100份出版物使用了该仪器的数据。 这些出版物解决了广泛的材料问题，包括聚合物共混物中的偏析和排序，化合物半导体器件中的相互扩散和金属接触，晶体生长的表征，以及离子-固体相互作用的基本原理。 这台机器目前正在全天候使用，以支持几个研究合同和项目，并涉及来自几所大学的教师以及工业界的研究人员。
