Developments of time-of-flight detector for mass measurements with the Rare-RI Ring

ORAL

Abstract

Development of the storage ring "Rare-RI Ring (R3)" for mass measurement of the short-lived RI is in progress at the RI Beam Factory in RIKEN. The mass-to-charge ratio of exotic nuclei is determined by the velocity of the nuclei and the revolution time of those in the R3.
We are developing the time-of-flight (TOF) detector which measures both velocity and revolution time in the R3. In our TOF detector, MCPs are used for detecting secondary electrons emitted from a thin foil where the ions pass through.
We measured time resolution for this detector with the 84Kr beams of 200 MeV/nucleons provided by Heavy Ion Accelerator in Chiba in National Institute of Radiological Sciences. In the conference, we will show the design of this detector and the result of the time resolution.
