Abstract: A traveling-wave tube is provided which has a heat radiating structure with good heat conductivity from the collector core to the heat sink. An insulator is disposed around and in contact with the outer peripheral surface of a collector electrode and has a slit in parallel with a tube axis. A radiator is disposed outside of and in contact with the insulator and has a slot formed on the top surface thereof extending in parallel with the tube axis. The radiator also has one or more grooves that insect the slot and receive therein a fastening member having a length shorter than the length of the groove and formed with screwed holes extending through both end portions thereof in the axial direction. By adjusting amounts by which bolts are screwed into the fastening member through the throughholes formed through the radiator, the gaps in the groove between the radiator and both end surfaces of the fastening member can be varied. This allows a fastening force to be transmitted from the radiator to the entire insulator, thereby readily adjusting the degree of contact between the radiator and insulator and collector electrode.

Abstract: A collector for a linear beam has a segmented ceramic collector core that permits sustained operation at high temperatures and power densities. The collector provides efficient heat transfer from the while reducing stresses on collector components caused by thermal cycling and comprises a heat sink having a cavity providing interior vacuum walls for the collector a segmented ceramic insulator disposed inside the cavity, and an electrode disposed inside and against the insulator. The insulator comprises sectors separated from one another by gaps, and may be notched in its outer surface for high-voltage stand-off from the sink. The electrode is preferably not brazed/soldered to the insulator. A stage of the electrode may be probeless and comprise a depression. A molybdenum-fabricated heat sink and stage assembly utilizes an insulator constructed from beryllium oxide, aluminum nitride, or alumina; alternatively, a copper assembly, uses an aluminum nitride insulator.

Abstract: An electron discharge tube evaporation cooling system in which part of a tube to be cooled is immersed in coolant in a boiler (15), the cooling system further comprising a condenser (18) for vapor generated in the boiler (15), and a coolant reservoir (11). The flow of vapor from the boiler (15) to the condenser (18) experiences resistance in the interconnecting pipe (17), producing in the boiler (15) a back pressure dependent on the dimensions of the pipe (17). In order that a desired level (40) of coolant in the boiler (15) can be obtained for a range of back pressures, the coolant is supplied to the boiler via an overflow system (16) having an adjustable overflow level. The overflow system (16) comprises a chamber (31) open to atmosphere at the top (34) and having at the bottom (33) an opening (36) through which an overflow tube (35) passes. The opening (36) is provided with a liquid-tight gland (37) comprising a compressible ring (42) and a pressure member (43) adjustable to allow the tube (35) to be slid through or to lock it in position.
