Cold Field Emitter Arrays for HPM

The Department of Defense, specifically the United States Air Force, is seeking proposals for the development of Cold Field Emitter Arrays for High Power Microwave (HPM) applications under the SBIR program. The objective is to create modular field emitter arrays that can generate electron beams as a viable alternative to traditional thermionic and explosive cold emitting cathodes, focusing on consistent performance, scalability, and durability. These arrays are intended for use in various devices, providing predictable current densities and high current capabilities, with proposals required to demonstrate small-scale array creation and metrics such as current density and lifetime. Interested parties should note that the solicitation is set to open on May 28, 2025, with a closing date of June 25, 2025, and can find more information at the provided source link.
