  • Patent number: 8952340
    Abstract: A high-frequency acceleration type ion acceleration and transportation apparatus is a beamline after an ion beam is accelerated by a high-frequency acceleration system having an energy spread with respect to set beam energy and includes an energy analysis deflection electromagnet and a horizontal beam focusing element. In the ion acceleration and transportation apparatus, a double slit that is configured by an energy spread confining slit and an energy analysis slit is additionally disposed at a position at which energy dispersion and a beam size are to be appropriate. The position is determined based on a condition of the energy analysis deflection electromagnet and the horizontal beam focusing element, and the double slit performs energy separation and energy definition and decreases the energy spread of the ion beam by performing adjustment for a smaller energy spread while suppressing a decrease in the amount of a beam current.

  • Patent number: 8768527
    Abstract: A power demand/supply management server (10) obtains information defining restraint contents to a comfort and an electricity bill from a consumer power operating device (2). An individual-consumer control optimizing unit of the power demand/supply management server (10) calculates control contents to an electrical equipment having a minimum cost evaluation value based on a simulation result of cost evaluation values which are barometers for evaluating a comfort and an electricity bill excessiveness, and transmits the calculated control contents to the consumer power operating device (2). Also, a whole-consumer optimizing unit of the power demand/supply management server (10) calculates the most appropriate electricity unit meter-charge that ensures a necessary demand suppression plan level throughout the whole power system based on an electricity daily load curve for each consumer.
