摘要:In the near future, short-lived and rare nuclei will be generated with a production rate of about one particle per day by uranium in-flight fission with an intensity of 1 particle micro-Amp at the accelerator complex in RIBF. Our apparatus, named “Rare-RI Ring”, will be constructed at the downstream of an in-flight RI-beam separator BigRIPS. It consists of three main parts: an injection line, a fast response kicker system, and a cyclotron-like storage ring. The combination of an injection line and a fast response kicker system enables us to inject short-lived rare nuclei into the isochronous ring one by one. The isochronous ring, which consists of six magnetic sectors and straight sections, allows us to determine the mass with an order of 10−6 precision for even only one particle, by measuring the revolution time of the particle under the condition of precise isochronism. Here, we report the present status of this project.
