The multipurpose synchrotron and tandem accelerators at WERC(W-MAST : Wakasawan Energy Research Center Multipurpose Accelerator System with Synchrotron and Tandem) can accelerate a proton up to 200 MeV, approximately 60% of the speed of light, or about 180 thousand km per second. This is equal to the speed traveling around the earth four times per second.

The particles accelerated by the tandem accelerator are used for various research works; for example, the elemental composition analysis of solids such as metals in Irradiation Room 1, the ion-injection into metal experiments in Irradiation Room 2, etc. The tandem accelerator also serves as the ion-injector for the synchrotron accelerator, so that accelerated protons are sent to the synchrotron accelerator.

Particles in the synchrotron accelerator travel around the track 2 million times maintaining a fixed orbit by magnetic intensity generated by electromagnet. And the particles accelerated to necessary energy are used for cancer therapy research in Irradiation Room 3, for breed improvement of plants including rice and buck wheat, etc. in Irradiation Room 4.

Two ion sources, a helium ion source and a plasma-sputtering ion source, are provided at WERC.

• It is a charge conversion type ion source, and used for supplying ions such as helium ion and hydrogen (proton) ion.

• It is used for supplying beams such as hydrogen (proton) beam and carbon beam.
