摘要： An amplifying device comprises an electron gun emitting an electron beam, a collector spaced from the electron gun, the collector oriented to collect electrons of the electron beam emitted from the electron gun, and an interaction structure interposed between the electron gun and the collector. The interaction structure defines an electromagnetic path along which an applied electromagnetic signal interacts with the electron beam. The interaction structure further comprises a plurality of polepieces and a plurality of magnets, the polepieces each having an aligned opening to collectively provide an electron beam tunnel having an axis extending between the electron gun and the collector to define an electron beam path for the electron beam. The polepieces provide a magnetic flux path to the electron beam tunnel from the magnets. More particularly, the interaction structure further includes plural cavities defined therein interconnected to provide a coupled cavity circuit. At least one of the plurality of polepieces separate adjacent ones of the plural cavities and have an iris for coupling the electromagnetic signal therethrough. At least one of the plurality of polepieces further has a void aligned perpendicularly to the beam tunnel axis.

摘要： An apparatus is disclosed that provides back light for liquid crystal displays ('LCD'). The apparatus includes an electrodeless lamp disposed in a cabinet for generating light; and a reflector disposed on one side of the electrodeless lamp for directing light from the lamp in the direction of the LCD. The reflector further includes a surface profile that provides a uniform distribution of light intensity into the LCD. The reflector further is adjacent and in near contact with the lamp to provide a minimum depth behind the lamp. An alternate embodiment of the invention includes an IR reflector disposed between the electrodeless lamp and a diffuser, which is located adjacent to the LCD screen.

摘要： A variable spot size x-ray tube comprises a cathode having an electron emitting surface providing an electron beam that travels essentially along the tube axis of symmetry to an anode. The anode, spaced from the cathode, includes a target, the front surface of which is disposed at an oblique angle with respect to the axis of symmetry. The potential of the anode is generally positive with respect to that of the cathode. The cathode is heated to a temperature at which electrons are emitted by the thermionic emission process. Current from the cathode can be controlled by varying the cathode temperature if the cathode is operated in the temperature limited region. The incident electron beam forms a spot on the target surface (38) whereupon x-rays are produced in response to impingement of the electron beam on the target. The x-rays propagate outwardly from the target spot through a vacuum window (42) to form a beam of x-radiation outside the x-ray tube. An aperture grid (18) is disposed between the cathode and the anode, and has a central aperture permitting the electron beam to pass therethrough. The aperture grid further has a variable voltage applied to it which may be positive, negative, or equal to the potential of the cathode. The voltage on the control grid is used to control the diameter of the electron beam which impinges upon the target. Specifically, the electron beam diameter varies in correspondence with the variable aperture grid voltage, and selective variation of the electron beam diameter results in a corresponding variation in size of the x-ray imaging spot.

摘要： A coupled cavity circuit for a microwave electron tube comprises at least two resonant cavities adjacent to each other. An electron beam tunnel passes through the coupled cavity circuit to allow a beam of electrons to pass through and interact with the electromagnetic energy in the cavities. An iris connecting the adjacent cavities allows electromagnetic energy to flow from one cavity to the next. The iris is shaped to cause the iris mode passband to be lower in frequency than the cavity mode passband while still providing broadband frequency response. In addition, the present coupled cavity circuit operates on an electron beam to interact with the third space harmonic of the second passband (the cavity passband) of the electromagnetic signal. Preferably, this interaction occurs on the second passband as this operational design provides output with higher frequencies without decreasing the cavity size. Furthermore, this operational design provides more frequencies with no increase to the iris size. This results in allowing higher power to be provided to the circuit without thermal degradation of the circuit. Also, because the interaction occurs on the third space harmonic of the second passband, the present operational design results in providing flatter frequency responses.
