灯丝预处理仪的研制

Development of an Instrument for Filament Preheating

报道团体同位素质谱计离子源灯丝的烧带处理仪的研制，该仪器一次可处理２０条灯丝，工作稳定可靠，性能良好，成本和价格远低于进口同类型仪器。

The development of an instrument for the preheating of filament used for solid isotope mass spectrometer is reported. Using this instrument impurities and pollutants in the filament are eliminated by heating the ribben. It can treat 20 ribbens simultaneously.Not only its performence is stable and satistactory,but also the cost is much lower than that of similar import instrument.
