发明名称 Mass Spectroscope and its Adjusting Method
摘要 In order to enable the mass spectroscope to reduce the operation load of the adjustment of the amplitude difference, and to reduce the increase in power consumption caused by the difference between the resonance frequency and the drive frequency, the resonance circuit unit of the ion trap section is configured to control the amplitude difference adjustment section of the resonance circuit unit to adjust that the amplitude difference between the high-voltage RF signals decreases, and controls the frequency synchronizing section of the resonance circuit unit to adjust that the resonance frequency of the resonance circuit is aligned with the drive frequency of the RF signal source, on the basis of the information about the amplitude difference between the high-voltage RF signals and the resonance frequency of the resonance circuit unit, which have been measured by a resonance frequency/amplitude difference measuring unit.
