High Frequency RF Components for Secondary Electron Emission and Multipactor Physics Studies
Abstract
The University of New Mexico (UNM) is a partner on an FY17 AFOSR Multidisciplinary University Research Initiative (Multipactor and Breakdown Susceptibility and Mitigation in Space-Based RF Systems) team led by Michigan State University. As part of its contributions, UNM will build upon its existing experimental capability for characterizing secondary electron yield. In the proposed effort RF test cells were being designed for multipactor studies at low frequency, around 1 GHz. The purpose of this instrumentation award is to acquire RF components at higher frequencies, 50 GHz and higher, to develop a test cell capable of studying multipactor at the extreme end of frequencies relevant to TWTs used in Space Communication (NASA is currently exploring 72/84 GHz in a terrestrial propagation link at UNM’s COSMIAC School of Engineering Center).This DURIP award will also be used to experimentally demonstrate a novel power combining scheme at high frequency [H. Seidfaraji, M.I. Fuks, C. Christodoulou, and E. Schamiloglu, “Efficient Power Combiner for THz Radiation,” AIP Advances, vol. 6, 085220-1-10 (2016)] that was sponsored by a DARPA INVEST grant. This instrumentation will be used to educate Ph.D. students that will then join the work force in this important discipline.
