This paper describes how a 94 GHz, 70 kV gyrotron operating in the TE13 mode was designed and built. The novel feature of the design is that it was based to a large degree on a previously built gyrotron that operated at a lower frequency. The highest

Our research shows that the presence of an oxide layer on the surface of a field emission cathode is deleterious to its performance and that, for successful operation, removal of this layer is necessary before overcoating with another material. We fu

We report the first demonstration of vacuum field emission from an electron source fabricated from self‐assembling biomolecular composite microstructures. Diacetylenic lipid DC8,9PC is used to form hollow, 0.5 μm diam, ≳50 μm long, tubelike str

We report on measurements of vacuum field emission from ungated field emission cathode arrays fabricated from Si‐TaSi2 eutectic composite wafers. The Si‐TaSi2 material is an ideal candidate for large area field emission array cathodes due to the
