Nanoprecision CNC Machining Center for Sub-THz to THz Vacuum Electronics
Abstract
ABSTRACT: We are requesting the purchase of a KERN Pyramid Nano Nanoprecision CNC MachiningCentre to support fabrication of sub-THz and THz devices and systems. It would support currentlyfunded programs including ~Commercialization of Nano-composite Tungsten Sc"andate Cathodes~ funded by Naval Sea Systems Command, Crane Division, and ~W-band Additive Vacuum Electronics~ funded by DARPA MTO a"s well as generally contribute to PEO IWS 2.0 needs. This advanced manufacturing machine would also open opportunities in developmen"t of high power,compact, wide bandwidth and high efficiency millimeter wave and THz vacuum electronics with applications in future"" electronic warfare and countermeasures programs, landmine detection, plasma imaging, as well as high efficiency electric space prop"ulsion and thermionic converters. It will also impact cost containment of deployed radar systems by enabling application of additive manufacturing techniques to manufacturing of microwave amplifiers. Additive manufacturing produces surface finishes of few tens to" few hundreds of micrometers; microwave devices need to have sub-micron level surface finishes for proper performance. Furthermore,"" the KERN machine will contribute to the development of millimeter-wave andsub-millimeter-wave interconnect transitions, and transm""ission media, which are used to bring highly integrated semiconductor circuits into system applications. It is also critical to the" development of advanced microwave and millimeter wave econfigurable components and systems as well as metamaterials and metasurfaces in which precision machining with extremely smooth surface finish is required. This machine is capable of holding tolerances to su"bmicrons and of producing excellent surface finishes (<100 nm Ra). When incorporated into the Davis Millimeter Wave Research Center,"" it would allow for production of complex high quality microwave circuits not only for UC Davis programs, but also for government an""d industrial partners. In addition, this machine can be used in combination with the additive manufacturing technologies to achieve" proper surface finish for high quality rf performance.
