Upgrading an X-Ray Energy Dispersive Spectrometer on the Electron Probe Microanalyzer for Materials Research and STEM Education at Fayetteville State University
Abstract
This proposal seeks fund to update an X-ray Energy Dispersive Spectrometer (EDS) on a JEOL JXA-8530F Electron Probe Microanalyzer (EPMA) at Fayetteville State University (FSU). The EPMA equipped with EDS was funded by the Army Research Office under Contract W9llNF-09-1-0011. Its Si(Li) EDS detector available at that time requires liquid nitrogen cooling. It is proposed to trade in the current detector to the manufacture and replace it with a liquid-nitrogen-free Silicon Drift Detector, which not only achieves improved performance with higher count rates, but a lso reduces maintenance cost and staff labor. The upgraded EDS detector will enhance the capability of the EPMA at FSU which is the sole field-emission instrument in the state of North Carolina, serving the academic, governmental and industrial communities for research and education. The acquisition of the proposed instrument will support five ongoing research projects at FSU: (I) Hig h-Efficiency X-ray Radiation Detection; (2) High-Efficiency Ultraviolet to Infrared Radiation Detection; (3) Shape Memory Alloy Nanowires for Deformation Behavior on Nanoscale; (4) Nanostructured Explosive Biosensors; and (S) Surface Treatment ofBiomaterials. The proposed EDS detector on the EPMA will be used to study the structure of these materials, advancing the research described in the Army Research Office Broad Agency Announcement for Basic and Applied Scientific Research (W91 INF- 12-R-001 2-02). FSU, located in Fayetteville City, North Carolina, is a His torically Black Colleague and University (HBCU) focusing on the education of African American and military students from the local Fort Bragg US Anny installation. Currently, a pproximate ly 75% of the student population is classified as minorities, primarily African Americans, and with a high female to male ratio (the ratio is greater than 2: 1). Among them, about 19% students are military related. The proposed instrument will be used for education to enhance current STEM (Science, Technology, Engineering, and Mathematics) educational programs at FSU.
