本文讨论了火花源质谱仪中火花离子源100kV高频高压的设计问题。分析了次级迴路为电感线圈和分布电容谐振的互感耦合迴路的调谐方法,即改变初级电容C_1和调谐振荡器角频率ω达到谐振,并与发射电子管的阻抗相匹配,从而使高频高压输出达到最大最大值。 This article discusses the design of spark ion source 100kV high frequency and high voltage in spark source mass spectrometer. The secondary loop is the tuning method of mutual inductance coupling loop with inductance coil and distributed capacitance resonance. That is to say, the primary capacitance C_1 and the angular frequency ω of the tuning oscillator are changed to resonate and matched with the impedance of the transmitting electron tube so that the high frequency and high voltage output Reached maximum maximum.
