    Abstract: An apparatus for generating electromagnetic waves is envisaged relating to the field of electromagnetic wave generating systems. The apparatus provides efficient radio frequency amplification, facilitates low loss electromagnetic generation, enables efficient utilization of kinetic energy of electrons, and works for different radio frequencies. The apparatus comprises an evacuated envelope, a pair of metal plates, a resonator, an electron gun, a magnetic field generator, and a pick-up loop. The evacuated envelope defines a space therewithin. The pair of metal plates defines a passage therebetween. The resonator is coupled to the pair of metal plates. The electron gun emits controlled bursts of electrons into the passage. The magnetic field generator is configured to generate electromagnetic waves. The pick-up loop extracts the generated electromagnetic waves.

    Abstract: A crossed field device for generating electromagnetic emissions includes an anode having a first slow-wave structure having a plurality of first vanes separated by cavities formed therebetween and a second slow-wave structure having a plurality of second vanes separated by cavities formed therebetween. At least one of the first vanes is laterally aligned with one of the second vanes. The first vanes are offset from the second vanes by an offset distance so that at least one of the first vanes is not laterally aligned with a second vane and at least one of the second vanes is not laterally aligned with a first vane. The device further includes a cathode disposed in a space located between first and second vanes. A magnetic element generates a magnetic field (B), which is oriented orthogonally to an electric field (E) formed by the anode and cathode to generate EM emissions.

    Abstract: A heat dissipation semiconductor package includes a chip carrier, a semiconductor chip, a heat conductive adhesive, a heat dissipation member, and an encapsulant. The semiconductor chip is flip-chip mounted on the chip carrier and defined with a heat conductive adhesive mounting area. Periphery of the heat adhesive mounting area is spaced apart from edge of the semiconductor chip. The heat dissipation member is mounted on the heat conductive adhesive formed in the heat conductive adhesive mounting area. The encapsulant formed between the chip carrier and the heat dissipation member encapsulates the semiconductor chip and the heat conductive adhesive, and embeds edges of the active surface and non-active surface and side edge of the semiconductor chip, thereby increasing bonding area between the encapsulant and the semiconductor chip. The side edges of the heat conductive adhesive and the semiconductor chip are not flush with each other, thereby preventing propagation of delamination.

    Abstract: An ion accelerator for use in an ion beam implanter. The accelerator forms milliampere beams of heavy ions such as boron and phosphorous in a configuration in which the terminal ion source is replaced by a neutral beam injector. The neutral beam is formed at ground by the conversion of a focused beam of positive ions to neutral ions in a charge exchange canal. The neutral beam so formed is stripped of one or more electrons in a gas or vapor filled canal in the high voltage terminal. A 180.degree. analyzing magnet located in the high voltage terminal analyzes and directs a selected charge state to an acceleration tube parallel to the neutral beam injection tube where the selected positive ions are accelerated to ground potential. To extend the energy range of the accelerator below the injection energy, a high voltage insulator is provided to insulate the ground end of the positive ion acceleration tube permitting the acceleration tube and terminal to be uniformly biased at a negative voltage to decelerate the beam to very low energies at a location close to the point of use. An accelerator assembly includes a 90.degree. analyzing magnet in the high voltage terminal.

    Abstract: A magnetron preventing increases of dark current by making an axial static magnetic field on a plane containing an inner surface of an end shield on the microwave output port side in the interaction space different from the static magnetic field on a plane containing an inner surface of the end shield on the cathode stem side. The interaction-space-side axial end of a peripheral portion of the end shield associated with the weaker static magnetic field is displaced a predetermined distance axially toward the interaction space from the axial ends of the magnetron vanes. In one embodiment, the axial static magnetic field on a plane containing an inner surface of the end shield on the microwave output port side in the interaction space is made stronger than the static magnetic field on a plane containing an inner surface of the end shield on the cathode stem side. This compensates for eccentricity of the axis of the cathode with respect to the axis of the anode vanes. Such eccentricity is greater on the microwave output port side remote from the cathode stem.
