加速器质谱计(简称AMS)是70年代后期发展起来的检测宇宙成因核素的有效手段,在地质学、海洋学、陨石学、考古学与天体物理学等学科有十分重要的应用价值。 AMS方法与一般β计数方法比较,具有灵敏度高(同位素丰度灵敏度可达10~(-16)),样品用量少,测量时间短和精度高等优点,近年来,国际上已有三十多个实验室建立了AMS装置,并做了大量的研究工作,从发展趋势看,还不断有所增加。但是,AMS技术在我国远
Accelerator Mass Spectrometer (AMS) is an effective method developed in the late 1970s for the detection of cosmic nuclides. It has very important application value in disciplines such as geology, oceanography, meteorology, archeology and astrophysics. Compared with the general β counting method, AMS method has the advantages of high sensitivity (sensitivity of isotope abundance up to 10 ~ (-16)), less sample usage, short measuring time and high accuracy. In recent years, more than thirty A laboratory established AMS devices, and made a lot of research work, from the development trend, but also continue to increase. However, AMS technology is far in our country
