| Abstract | The Rare-RI Ring (R3) is an isochronous storage ring to determine the masses of short-lived rare nuclei with a relative precision of the order of ppm even for only one particle by measuring its revolution time. There are two crucial techniques for realizing the measurement as described above. As first one, a self-trigger scheme with a fast kicker system* allows us to inject the rare nuclei, which are produced by a DC primary beam from cyclotrons, into the R3 event by event. As second one, the R3 consists of only dipole magnets with trim-coils to precisely optimize the isochronism of circulating particles in a wide momentum range. After the construction was finished, we examined the basic performance of the R3 devices, i.e. injection line, septum magnets, dipole magnets, and fast kicker system by an alpha particle from a source. An α particle was injected by the self-trigger scheme successfully and extracted after storage for about 20 μs. The machine study of R3 using a beam is scheduled in June 2015. In this conference, we will discuss the technical aspects including the results of the machine study and of the basic performance examination. | |||||
