THE NEW EXTERNAL ION SOURCES AND THE NEW AXIAL INJECTION SYSTEM AT RCNP

摘要

A new polarized ion source and a new axial injection system have been constructed at RCNP in order to increase beam intensities and to get high quality beams. We get a proton current of 50 μA in the axial injection system. The polarization of the proton accelerated by a cyclotron is 70% or more. Beams from an ECR heavy ion source were successfully injected into AVF cyclotron through the new axial injection system at the end of September, 1994. We use a spiral inflector instead of the old mirror system to obtain good transmission of beams.
