I/UCRC FRP: Electron Beam Atomic Spectroscopy (EBAS)

该提案为位于伍斯特理工学院（WPI）的资源回收和再循环中心（CR3）寻求资金。基础研究的资金申请由NSF批准的征求授权，NSF 11-570。本次招标邀请I/ ucrc提交支持行业定义基础研究的提案。提出的“电子束原子光谱”（EBAS）是一种通过测量电子束撞击目标材料时产生的原子发射光谱来确定元素组成的方法。尽管EBAS背后的机制还没有被很好地理解，但EBAS有潜力大大减少能源使用，并提高工业过程的生产率，这些过程可以在制造零件时使用它进行过程控制。在这些工艺中，高价值和关键金属是通过熔化回收废料生产的。EBAS的一个关键特性是它的检测下限（LOD）比传统测量方法低得多，特别是在工业现场使用的测量方法。使用EBAS，结果几乎可以立即提供，这使得操作人员可以减少熔化时间，因为合金化也可以几乎立即完成。这节省的时间意味着更少的能量用于熔化和合金，更多的时间可以在炉上生产额外的产品。所提出的工作有可能以以前没有做过的方式优化高温金属的回收和再循环。潜在的影响是发展一种新的金属真空加工测量技术。该中心将鼓励高中学生和教师以及少数民族学生参与其中。PI将把K-12扩展到WPI现有的项目中。感兴趣的高中生将被邀请到金属加工研究所，并在PI和研究生的指导下参与与拟议研究相关的子项目。

This proposal seeks funding for the Center for Resource Recovery and Recycling (CR3) located at the Worcester Polytechnic Institute (WPI). Funding Requests for Fundamental Research are authorized by an NSF approved solicitation, NSF 11-570. The solicitation invites I/UCRCs to submit proposals for support of industry-defined fundamental research. The proposed study "Electron Beam Atomic Spectroscopy" (EBAS) is a method to determine elemental compositions by measuring the atomic emission spectra produced when an electron beam impinges on a target material. Although the mechanisms underlying EBAS are not well understood, EBAS has the potential to greatly reduce the energy use and improve the productivity of industrial processes that can use it for process control while manufacturing a part. In these processes, high value and critical metals are produced by melting recycled scrap. A key property of EBAS is its potential to have much lower limits of detection (LOD) than conventional measurements, especially of those used at industrial sites. With EBAS, the results are provided nearly instantly, which allows the operator to reduce the melt time as alloying can also be done nearly instantly. This saved time means less energy is used to melt and alloy and more time is available on the furnace to produce additional product.The proposed work has the potential to enable the optimization of the recovery and recycling of high temperature metals in ways that have not been done previously. The potential impact is the development of a new measurement technique for vacuum processing of metals. The center will encourage high school students and teachers, and minority students to be involved. The PI will integrate the K-12 outreach into the existing program at WPI. Interested high school students will be invited to the metal Processing Institute and participate in sub-projects associated with the proposed research under the supervision of the PI and graduate students.
