Abstract
A multiturn-injection method has been used in the HIMAC synchrotron to obtain higher beam-intensity. Total and partial efficiency of multiturn injection are measured. The stored beam-intensity and its lifetime were considerably decreased above 600 μA for an injection current of alpha ions with 6 MeV/n, mainly due to the space charge effect on the transverse tune. A dependence of a stored intensity on vertical tune is investigated and the tune-shift is measured by the space charge effect
