Abstract
An accelerator mass spectrometer (AMS) utilizing a small cyclotron has been designed. The system has a mass resolving power of over 4000, which is su cient to analyze a few AMS radioisotopes, including 14C, for tracing or chronometric dating. The cyclotron can provide a high resolving power with a large number of turns and a high harmonic operation of the rf system and has the advantage of using both negative and positive ions in the analysis. A high transmission e ciency is, in fact, a major goal in the design to compete with a Tandem AMS. A compact magnet with high stability, a sawtooth harmonic buncher and at-topping rf system are the components adopted to achieve the goal. Also, large turn separations at injection and extraction are required, which can be done with adequate uses of the rst harmonic component of the main magnetic eld. The design of the cyclotron and injection beam line for the AMS has been studied.
