TI - Development of Low-Energy Heavy-Ion Beams by the RIKEN AVF Cyclotron and Hyper ECR Ion Source of CNS J2 - Proc. of Heavy Ion Accelerator Technology Conference (HIAT2015), Yokohama, Japan, 7-11 September 2015 AB - The application of low-energy heavy-ion beams enhances production of radioisotope (RI) and studies of nuclear astrophysics.　The Center for Nuclear Study (CNS) of the University of Tokyo and RIKEN Nishina Center have been developing the RIKEN AVF Cyclotron (AVF) and the Hyper ECR Ion Source (IS) of CNS to expand available ions and their acceleration energies as well as to increase the beam intensity for studies at the low-energy RI beam separator CRIB * and others. Renovation of central region of the AVF expands the acceptance of injection beam, so that 4He beam is now available at a higher energy of 12.5MeV/u under the constraint that the maximal Dee voltage is 50kV. Intensities of metallic ions extracted from the IS have been increased by developing three kinds of vaporization methods, multi-hole micro-oven, non-axial rod and MIVOC. Plasma spectroscopy ** is applied to monitor the intensities of highly charged ions in the IS. For systematic study of transport efficiencies, several beam diagnostic devices have been added. One key device is a set of a multi-hole slit and a viewer of the beam image (pepper-pot emittance monitor ***), which gives four-dimensional phase space.
