Abstract
A magnetron operating at a wavelength of 10 cm has been constructed with six resonant cavities cut in a cylindrical anode block. A graphite cylinder acting as a field-emission cathode delivers ∼12 kA in an accelerating radial potential of ∼360 kV. The magnetic field directed along the diode axis is ∼8 kG. Linearly polarized microwaves of 30 nsec duration at powers of ∼1.7 GW are achieved. The conversion efficiency of electron energy into microwave is ∼35%.Keywords
