摘要：

An integral part of any vacuum rf device is the cathode. Many rf and microwave tubes utilize thermionic cathodes. However, these cathodes are generally limited to current densities less than 100 A/cm(2), a limitation too great for the majority of High Power Microwave (HPM) tubes. At the Air Force Research Laboratory, Directed Energy Directorate (AFRL/DE), we have to study a variety of explosive emission cathodes. This paper presents results on studies of several types of cathodes tested in a simple circular geometry. We also present results of research on different types of anode material. The data includes measurements of current, voltage, cathode lifetime, and cathode/anode out-gassing.
