0922962Goeckner"This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5)."In this project, the applicants propose the development of a novel chemical analysis technology. Analysis of chemical species has been important to many technological advances. Current technologies rely on adsorption spectroscopy, inductively coupled plasma-atomic emission spectroscopy (ICP-AES), mass spectrometry (MS), gas chromatography (GC) and a few other diagnostics. Depending on the industry, there is often one tool that is considered the standard. For example the EPA sets pollution standards based on the capability of GC tools which employ ICP-AES tools within the system. The PI proposes to complete the basic development of a new diagnostic system that has the potential to replace ICP-AES and thus revolutionize both emission spectroscopy studies as well the capabilities of GC systems. Specifically the new tool is based on the use of well characterized variable electron beams to produce the emission. By employing a variable electron source, the density of the electrons can also be controlled independent of the electron energy. This change allows the development of a new class of emission spectroscopy tools that are inexpensive, easy to calibrate and allow direct density measurements.

0922962 Goeckner“该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。“在这个项目中，申请人提出开发一种新的化学分析技术。化学物种的分析对许多技术进步都很重要。目前的技术依赖于吸附光谱法、电感耦合等离子体原子发射光谱法（ICP-AES）、质谱法（MS）、气相色谱法（GC）和一些其他诊断法。根据行业的不同，通常有一种工具被认为是标准。例如，EPA基于系统内采用ICP-AES工具的GC工具的能力来设定污染标准。PI建议完成新诊断系统的基本开发，该系统有可能取代ICP-AES，从而彻底改变发射光谱研究以及GC系统的能力。具体地说，新的工具是基于使用良好的特征可变电子束产生的排放。通过采用可变电子源，还可以独立于电子能量来控制电子的密度。这种变化允许开发一种新的发射光谱工具，这种工具价格低廉，易于校准，并允许直接测量密度。
