摘要： This invention concerns a traveling wave amplifier of pillbox configurationhat can be made for battery operation. It has a high perveance cylindrical electron gun between closely spaced, parallel, flat surfaces of a pair of thin ceramic disks sealed at their perimeters to a conductive collector ring coaxial with the electron gun. One or both of the disks support a novel planar slow wave circuit. The slow wave circuit is termed a ring-bar circuit but differs from cylindrical ring-bar structures. It includes a series of concentric conductive rings. Along one diameter of the rings, to one side of the center of the rings, the first and second, third and fourth, fifth and sixth rings, etc., are conductively connected, and to the other side of the center of the rings, the second and third, fourth and fifth, sixth and seventh rings, etc., are conductively connected. RF feed connections are made to the first and last rings of the slow wave circuit opposite their connections to the second and next to last rings, respectively. A ring-bar circuit is printed on the inside surface of one or both of the ceramic disks or is constructed of wire and ribbon and is supported by the disk(s). If only one disk supports a ring-bar circuit, the other disk carriers a flat annular conductor of the same inner and outer diameters as the ring-bar circuit. If needed, focusing magnets are supported contiguous the outer surfaces of the disks. This invention can be made for operation with band-width as low as 2% and at high efficiency.

摘要： A semiconductor is positioned as the anode of an electron tube, and is borded with a radio-frequency modulated stream of electrons. This bombardment produces carrier pairs in the semiconductor in a well known manner. However, in this case the carrier pairs are bunched, in the same manner as the modulating electrons, as they are drawn through the semiconductor by its bias voltage. A radio-frequency coil or meander line adjacent to the semiconductor interacts with the bunched carrier pairs traveling through the semiconductor -- in the same manner as the radiofrequency coil of a traveling wave tube interacts with the electrons of a traveling wave tube, as they become bunched -- to produce an amplified r-f signal in the coil.
