The Department of Defense, specifically the Army branch, is seeking proposals for the development of a portable Diamond Nitrogen-Vacancy (NV) Center-based Quantum Magnetometer aimed at enhancing the detection of Person-Borne Improvised Explosive Devices (PBIEDs). The objective is to create a highly efficient magnetometer that leverages the advanced sensitivity and spatial resolution of Diamond NV technology to identify subtle magnetic signatures associated with explosives, particularly in challenging environments where traditional detection methods fall short. This initiative is critical for improving public safety and security, as it addresses the pressing need for effective explosive detection solutions. Proposals are due by July 30, 2024, with the solicitation number 24.4, and interested parties can find more information at the provided source link: https://www.dodsbirsttr.mil/topics-app/.
