Abstract

K2500 - superconducting ring cyclotron with 6-sectors is being constructed at RIKEN as one of the energy booster of the existing K540 ring cyclotron. The bending magnet for beam injection should be superconducting. Required fields are 3.8 T and radius of the coils is 1.2 m. After the fabrication, it was cooled down and excited. The magnet reached the designed field with one quench and training effect were clearly observed, which shows that it will works well to inject the beam into the superconducting cyclotron.
