    Abstract: An optical communication system is provided which includes an optical signal transmitter which communicates high bandwidth, high power frequencies. The optical signal transmitter includes a high efficiency/high power optical source such as an optical magnetron or a phased array source of electromagnetic radiation, and a modulator element. The modulator element may be within a resonance cavity of the high efficiency/high power optical source (intra cavity) or external to the cavity (extra cavity). The modulator element serves to modulate output radiation of the high efficiency/high power optical source to produce a modulated high frequency optical signal which may be transmitted through the air. The optical signal transmitter is particularly useful in providing the last mile connection between cable service operators and end users.

    Abstract: In a magnetron anode, an anode surrounds a central cathode. The anode is of a segmented structure having a plurality of annular segments stacked together along its length. Each annular segment includes a strap, the strap being distributed substantially along the entire axial length of the anode vanes. This enables mode separation to be achieved, even for long anode lengths and, hence, permits high power operation to be achieved. In addition, the segmented structure of the anode gives a mechanically robust design.

    Abstract: In a magnetron apparatus and a manufacturing method of the present invention, the magnetron apparatus comprises an anode cylinder, and a plurality of plate-form anode segments radially arranged around a central axis of the anode cylinder inside the anode cylinder. The anode segments are pressed against an inner surface of the anode cylinder by a pin press-fit into the central portion of the anode cylinder, and a far-end-side end surface each of the anode segments is secured to the inner surface. A concave is provided in the central portion of an inner end surface where the anode segments come into contact with the pin.

    Abstract: A traveling wave tube having an electron gun and a collector assembly is provided. The assemblies include a sleeve placed around an isolator. The sleeve is either heat shrunk or heat deformed around the isolator. Heat shrinking is performed when the sleeve radius is initially larger than the isolator radius. During heat shrinking, the sleeve is heated to cause the sleeve radius to increase and be larger than the isolator radius. The sleeve is then placed around the isolator and cooled causing the sleeve to contract upon the isolator. Heat deformation is performed when the sleeve radius is initially smaller than the isolator radius. During heat deformation, the isolator is inserted into the sleeve. The isolator and the sleeve are then heated so that the sleeve expands to a constrained amount of expansion and then deforms. The sleeve and the isolator are then cooled causing the sleeve to contract upon the isolator.

    Abstract: In order to provide a method of producing magnetron anode at a good mass-produceability, according to the invention, so-called straight type steel cylinder blank the inner peripheral surface of which is not tapered is used and, at the same time, the step of quench-hardening of the steel cylinder blank is omitted. After fitting a copper block to the inside of the straight type steel cylinder blank which has not been quenched, both members are compacted to each other. Then, a press working is effected on the copper blank such that the steel cylinder blank and a back-up punch are forced to move relatively to each other, when a press-working shaping punch is forced into the copper block, thereby to form a copper anode. In order to avoid the bursting of the steel cylinder blank, the press work on the copper block is effected at a temperature of 200.degree. to 650.degree. C.
