Accelerator mass spectrometry (AMS)is the most important tool for detection of naturally produced long-lived radioisotope. Absolute AMS-measurements of ^36Cl require reliable standards for calibration. This original solution of RM12492 was diluted for new AMS standards. All dilution solutions weremade gravimetrically.展开更多

Following the first success of accelerator mass spectrometry (AMS) in detecting ^14C by Muller in 1977, its technique was rapidly embraced by the low energy nuclear physicists with encouragement from several archaeologists, biologists and environmental scientists.Subsequently, several smaller and not so smallel ectrostatic tandem accelerators have been resurrected as AMS machines, and many nuclear physics laboratories have commenced their AMS research program. In parallel, a number of new facilities which are dedicated to the AMS studies have been constructed. Up to now, more than 40 AMS laboratories are active around the world (Fig. 1). 4 AMS laboratories are actively operating in China. 8 AMS laboratories which are working in Japan are listed in Table 1. In this talk, I will look briefly at the development of the field, will survey its current status, especially the effort of the Japanese group, and will mention about the future.展开更多
