加速器质谱的小型化及多核素测量是当今加速器质谱重要的发展方向。但对于具有同量异位素干扰的中重核素(如36Cl和41Ca),要在小型化的AMS系统上实现对其的高灵敏测量是很困难的。充气飞行时间探测(GF-TOF)方法是一种综合能量测量和时间测量的优点,利用能量与时间符合测量进行粒子鉴别的新方法。前人的研究工作表明,在低能量下充气飞行时间探测方法较其他方法是有优势的,很有希望在端电压为3MV左右的AMS装置上实现36Cl的高灵敏测量,因此, Accelerator mass spectrometry miniaturization and multi-nuclide measurement is an important development direction of accelerator mass spectrometry. But for medium and heavy nuclides with isobaric interference (such as 36Cl and 41Ca), it is very difficult to achieve highly sensitive measurement on a miniaturized AMS system. The Inflatable Flight Time Detection (GF-TOF) method is a new method that combines the advantages of energy measurement and time measurement with the use of energy and time to measure particles. Previous work shows that the method of detecting the time of flight of inflatable air at low energy is superior to other methods and it is very promising to realize the high sensitive measurement of 36Cl on the AMS device with the terminal voltage of about 3 MV. Therefore,
