Abstract

TARN II is a heavy ion cooler synchrotron for accelerator, atomic, and nuclear physics studies, which is presently being constructed at the Institute for Nuclear Study, University of Tokyo. Its maximum energy is 370 MeV/u for ions of a charge to mass ratio of 1/A=0.5, corresponding to a magnetic rigidity of 6.1 T-m. The circumference is 77.76 m, 17 times the extraction orbit of the injector cyclotron. It has six long straight sections of 4.2-m length each. These are used for the beam injection system, an RF cavity, an electron cooling device, and a slow beam extraction system. At the beginning of 1989, the first beam-injection experiment was performed successfully using 28-MeV α particles. The status and initial results of TARN II operation are presented
