eBeam is an R&D operation specializing in thermionic cathodes and vacuum electron devices, especially electron guns and microwave tubes such as klystrons and traveling wave tubes. eBeam provides consulting services, design, prototyping and testing on a broad range of vacuum electron devices to NASA, tDOD and private industry. Experience among the firm's personnel is broad, drawing from both the microwave tube and display tube industries. The firm has developed a high performance oxide cathode for space communications, along with reservoir cathodes and a low-power miniature dispenser cathode. They also developed a low cost electron gun, an electrostatically-focused traveling wave tube and a multibeam electrostatically-focused klystron for the NASA Glenn Research Center, and the ion source for a wind temperature spectrometer for the NASA Goddard Space Flight Center.
