    Abstract: An apparatus for generating filtered light may include a broadband illumination source configured to generate broadband illumination and a total internal reflection (TIR) filter formed from a material at least partially transparent to the broadband illumination. The TIR filter may include one or more input faces oriented to receive the broadband illumination. The TIR filter may further be oriented to reflect wavelengths of the broadband illumination beam below a selected cutoff wavelength on one or more filtering faces as filtered broadband illumination and provide the filtered broadband illumination beam through one or more output faces. The cutoff wavelength may further be selected based on total internal reflection on the one or more faces.

    Abstract: An electrode of an inductive output tube (IOT) is provided with channels for guiding cooling fluid. In one aspect of the invention, the channels are in a confronting relationship with a jacket surrounding the electrode and spaced from the electrode so as to define an interior region. Cooling fluid such as oil is circulated in the channels in fluid communication with the interior region, providing an escape mechanism for trapped bubbles in order to prevent localized heating of the electrode. In another aspect of the invention, the channels form multiple intersecting helical patterns of different pitches, with the steeper-pitched channels providing a more direct escape route for the bubbles.

    Abstract: A collector for a travelling-wave tube includes a collector core and a fin structure surrounding the core and having a plurality of fins for heat radiation. An oxide film having a thickness of greater than 50 .mu.m inclusive is formed on the outer periphery of the fin structure by anodization and has the maximum surface roughness of 12 .mu.m inclusive. When the 50 .mu.m or thicker oxide film is sealed or when a 45 .mu.m or thicker oxide film is formed and sealed, the oxide film is provided with the maximum surface roughness of greater than 12 .mu.m inclusive. The collector with any one of such structures achieves an emissivity of 0.90 or above and can efficiently radiate heat generated by the tube in the space.

    Abstract: Cooling apparatus of a magnetron having a plurality of embossed cooling fins for radiating high temperature heat generated by an anode of the magnetron. Each of the cooling fins includes an anode support boss for tightly receiving and supporting the anode, a pair of erected walls being provided at both sides of the cooling fin, and a plurality of embossments for causing cooling airflow to be forced toward the rear surface of the anode and providing a cooling passage. These embossments are provided between the anode and the erected walls in order to symmetrical to each other with respect to the cooling airflow. The embossments comprise a plurality of protruded embossments provided at a side of the cooling fin and a plurality of depressed embossments provided at the other side of the cooling fin. The protruded and depressed embossments have an interval which is gradually shortened such that it is minimized at the rear of the anode. In accordance with this invention, the cooling air is forced toward the rear surface of the anode and, as a result, the separation region of the rear surface of the anode is remarkably reduced. The friction between the cooling air and the cooling fins is increased due to the embossments, thereby improving the cooling effect of the magnetron.

    Abstract: To increase production of magnetrons, a spiral fin is wound on a magnetron body as soon as it is produced, and a leading end and a trailing end of the fin are fixed to the magnetron body. This increases the number of turns of the fin wound on the magnetron body and improves the bond strength with which the fin is bonded to the magnetron body to thereby increase the effect achieved by the fin in dissipating heat and avoiding a decline in the performance characteristics of the magnetron.
