A quasi-monoenergetic neutron field was developed using the 7Li(p, n)7Be reaction in the energy range from 70 to 210 MeV in the ring cyclotron facility at RIKEN. Neutrons were generated from a 10-mm-thick 7Li target injected by protons accelerated to

Slow positron beams were extracted by irradiating various targets with p + , d + and He 2+ ion beams from the AVF (azimuthally varying field) cyclotron of RIKEN. The targets were selected considering the large cross section and high maximum energy of

Using the RIKEN AVF cyclotron, various targets were irradiated with proton or deuteron beams to produce β+-decay radioisotopes. Slow positrons are extracted backward at an angle of 30° to the incident ion beam using a well annealed W film, with a t

The accelerator complex of the proposed IPCR heavy-ion facility consists of a separated-sector cyclotron (SSC), a variable frequency linac, and an AVF cyclotron. The linac and AVF cyclotron are used independently or serve as injectors for the SSC. Th
