Status of the Berkeley Small Cyclotron AMS (Accelerator Mass Spectrometry) Project

摘要

A small, low-energy cyclotron has been designed and built at Berkeley for direct detection dating of sup 14 C. The system combines the use of a negative ion source to reject sup 14 N with the high resolution of a cyclotron to reject other background ions. In order to allow the dating of old and small samples, the present system incorporates a high-current external ion source and injection beamline. The system is expected to be operational by mid-1987.
