PRODUCTS & SERVICES
In 1972, Sumitomo Heavy Industries built the largest AVF cyclotron in Japan at the time. Since then, we have been providing a multiplicity of accelerators for research and development institutions in Japan, and have been developing diverse accelerator technologies, including the high energy ring cyclotrons and standard AVF cyclotrons for heavy ion experiments and RI production, in addition to ECR ion source and RFQ and drift tube linacs as the injector of heavy ion synchrotrons. We have also developed electron synchrotrons as synchrotron light sources, as well as its injector microtron. We are committed to advanced research in physics, chemistry, and other science disciplines that utilize nuclei, molecules, heavy particles, and synchrotron radiation.
A cyclotron is a charged particle accelerator in an axial magnetic field, which utilizes high frequency (Radio Frequency, RF) electric field to accelerate the charged particle beam which is spiraling on a plane perpendicular to the direction of the magnetic field.
LINAC as injector for carbon ion therapy
In a linear accelerator (linac) high frequency electric field accelerates the charged particles travelling axial direction.
Synchrotron Radiation Source (SR ring)
Synchrotron radiation (SR) is light radiated tangentially when high energy electrons are bent by a magnetic field.
