  • Patent number: 9736922
    Abstract: The deviation of an electron beam is measured in a drift tube of a linear accelerator, the wave to be decoupled having a frequency range that corresponds to a multiple of the basic frequency of the acceleration field. Coupling probes, a mixer-based receiving concept with high dynamics and sensitivity, a method for evaluating the measuring signals and a calibration method for calibrating out non-linearities are specified. Disruptive influences through the acceleration field are minimized by the measurement method according to the invention and the frequency range to be evaluated. The high evaluated frequencies also offer geometrically small coupling probes which one can introduce into a drift tube in which only the field of the electron beam to be evaluated exists.

  • Patent number: 8354779
    Abstract: A heat sink for an LED downlight utilizes tilted fins forming helical air passages that can enhance thermal performance by 30% over conventional fins. To overcome the thermal challenge of installation within the stagnant hot air of insulated ceiling cans, a heat sink has an integral electrostatic air pump on its exterior, to move hot air downwards and drain the stagnant air from the can by establishing a chimney-like circulation up through the heat sink and back down around the outside of the heat sink. The air mover can be powered by a compact high-voltage, low-current power supply similar to those of neon signs. An embodiment of the heat sink is also revealed that is suitable for cooling an LED replacement for standard screw-in or equivalent light bulbs. This device can perform well in variety of orientations (horizontal, vertical, etc.) and fixtures.

  • Patent number: 6885134
    Abstract: In a light source, a heat sink is in contact with a side-on type discharge tube 110. The heat sink is in contact with a peripheral region 110ws around an exit window 101ww of the discharge tube 110. The heat sink consists of a spring member 101sp kept in direct contact with the peripheral region 101ws, and a radiating block 101bl which connects the spring member 101sp to a radiator box 101bx. Since materials made by sputtering or the like of electrodes in the discharge tube 110 mostly attach to the peripheral region 101ws of side wall 101w, it is feasible to decrease the amount of materials attaching to the exit window 101ww and, in turn, lengthen the lifetime of the discharge tube. Another light source may be constructed in structure in which the heat sink is in contact with a head-on type discharge tube or in structure in which light is outputted from a projecting portion.
