摘要： PURPOSE:To minimize the movement of the tuner so as to improve the reliability and the life time of a cavity resonator by controlling the circulating flow rate of coolant basing on the temperature of the cavity body detected with a temperature detecting means. CONSTITUTION:The temperature of a cavity body 10 is detected with a thermometer 11 and compared with a preset temperature with a flow rate controller 12, and when the preset value is higher than the detected value the opening of a flow rate controlling valve 13 is increased depending on the temperature difference. On the other hand, when the preset value is lower than the detected value the opening of the flow rate controlling valve 13 is decreased depending on the temperature difference. Thereby the flow rate of pure water flowing in a cooling tube 5 is controlled by the said valve 13 so as that the temperature of the cavity body is kept nearly at the preset temperature. Thereby when adjusting the resonance frequency the movement of the tuner can be minimized to obtain an accelerating cavity resonator of high reliability and long life time.
