  • Patent number: 7683556
    Abstract: In an acceleration tube conditioning apparatus for performing a conditioning process on an acceleration tube when a high frequency power signal to be supplied to an acceleration tube is generated by a high frequency power supply, a power value collecting section collects a traveling wave power value and a reflection wave power value from a sensor which monitors the traveling wave power signal and the reflection wave power signal. A high frequency calculating section calculates a resonance frequency of the acceleration tube based on the traveling wave power value and the reflection wave power value. A high frequency adjusting section determines a high frequency value based on one of the traveling wave power value and the reflection wave power value as a selection power value, and a high frequency power supply control unit controls the high frequency power supply based on the high frequency value.

  • Patent number: 7419529
    Abstract: An object of the present invention is to provide a method of forming fine particles on a substrate in which reoxidization of reduced fine particles is suppressed. Reduced fine particles (FeO fine particles) are formed by embedding metal oxide fine particles (Fe2O3 fine particles) fixed on a p type silicon semiconductor substrate into a silicon oxidized film, and carrying out a heat treatment in a reducing gas atmosphere. Presence of the silicon oxidized film enables suppression of reoxidization of the reduced fine particles (FeO fine particles) due to exposure to the ambient air.
