  • Patent number: 9617970
    Abstract: A pumped storage power plant for a temporary reversible storage of energy, such as the energy available from wind power stations and/or photovoltaic systems that is fluctuating over time. The pumped storage power plant is designed as an underwater pumped storage power plant, wherein the ocean assumes the function of an upper storage basin and a pressure tank placed on the ocean floor serves as a lower storage basin. The storage of the electric energy takes place through pumping water out of the inside of the pressure tank against the hydrostatic water pressure on the ocean floor.

  • Patent number: 6624584
    Abstract: The invention relates to a particle source, particularly an ion source for the production of excited particles in gaseous media. A dielectric, e.g., Kapton foil, is coated electrically conductively on both sides, and a voltage, preferably pulsed, is applied between the two coatings. A gas discharge is ignited in the gas through-flow by the voltage. Due to a pressure difference between the two sides of the foil, the gas expands from the high pressure side to the low pressure side, preferably in an ultrasonic expansion, whereby a directed, cold beam of excited particles or ions is produced.

  • Patent number: 5686721
    Abstract: A method and apparatus for image signal decoupling in position-transmitting high-vacuum electromagnetic radiation quanta or particle detectors. The electromagnetic radiation quanta or particles impinge on a spatially resolving anode structure through a photoelectron converter layer (in the case of electromagnetic radiation) and directly through an electron multiplier as an electron avalanche (in the case of particle radiation). The electron avalanche is first collected for a short time inside the vacuum on the anode side by means of a high-resistance, conducting semiconductor thin film, and is then read out capacitively from the outside through the glass bottom (counter-substrate) of the detector device as an image charge by means of a low-resistance anode layer of suitable structure. The capacitive decoupling permits high spatial resolution when the internal resistances of the charge collecting layer and the readout anode layer are optimally adapted to one another.
