Abstract :
A Test Accumulation Ring for NUMATRON Project, TARN, is now under construction at INS, University of Tokyo. Heavy ions from the SF Cyclotron such as N5+ with an energy of 8.5 MeV per nucleon, are planned to be injected and stacked in the ring by a combination of multiturn injection and RF stacking method Expected intensity of the stacked beam, e.g. N5+, is 2 × 1010 particles, and a survival rate of 90 % is anticipated at the pressure of 1 × 10-10 torr during a stacking time of 1 sec. In this paper, the present status of the ring is described as well as the performances of the major subsystems.
