The cyclotron-based accelerator device can accelerate a proton up to an energy of roughly 30 MeV. When the proton contacts the beryllium target, fast neutrons are created that travel through a beam shaping assembly made of calcium fluoride, lead, iron, and aluminum to lower the neutron energy to the epithermal region, which is ideal for BNCT (10 keV). With a proton current of 1 mA, the system is intended to produce epithermal neutron flux of up to 1.2×10⁹ cm⁻² s⁻¹. In 2017, the same type of accelerator was installed at the Kansai BNCT Medical Center and in March 2020 the system received medical device approval in Japan (Sumitomo Heavy Industries, NeuCure® BNCT system). Soon after, BNCT for unresectable, locally advanced, and recurrent carcinoma of the head and neck region was approved by the Japanese government for reimbursement covered by the national health insurance system. Thus far, over 100 patients have been treated using this system.
