Unlike accelerator mass spectrometry (AMS) performed in combination of a negative ion source + a tandem accelerator, a new accelerator mass spectrometry was developed that combines a positive ion source (ECR ion source), a heavy ion linear accelerator (RILAC) and an ionization chamber with multipolar electrodes as particle detection. We will announce some experimental results that have been carried out with this system. The introduction techniques of the solid samples and the feature of ionization in the ECR ion source will also be described in detail.
