This award supports the update of an X-ray Energy Dispersive Spectrometer EDS on a JEOL JXA-8530F Electron Probe Microanalyzer EPMA at Fayetteville State University FSU. The EPMA equipped was funded by the Army Research Office under Contract W911NF-09-1-0011. Its original SiLi EDS detector available at that time required liquid nitrogen cooling. It was proposed to trade in the original detector to the manufacturer and replace it with a liquid-nitrogen-free Silicon Drift Detector, which not only achieves improved performance with higher count rates, but also 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 1 high-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 5 surface treatment of biomaterials. 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 W911NF-12-R-0012-02. FSU, located in Fayetteville City, North Carolina, is a Historically Black Colleague and University HBCU focusing on the education of African American and military students from the local Fort Bragg US Army installation. Currently, approximately 75 percent of the student population is classified as minorities, primarily African Americans, and with a high female to male ratio the ratio is greater than 21. Among them, about percent students are military related.
