Latest Patents

Kawasaki's latest patents include a transportable linear accelerator system and a transportable neutron source equipped therewith. This innovative system aims to restrain the entry of losing ion beams that deviate from their intended trajectory. By doing so, it efficiently reduces radioactivity at a low cost. The system is designed with a beam chopper positioned just before the inlet of a post-accelerator. This configuration allows for the cutting off of uncontrolled proton beams, ensuring that only controlled proton beams are radiated to the post-accelerator. This prevents the proton beams from hitting critical components like the acceleration electrode of the post-accelerator.

Another notable patent is the synchrotron injector system and operating method for drift tube linear accelerators. This invention involves feeding radio frequency power to the drift tube linear accelerator while accelerating first ions. The phase difference between the accelerating half cycles is carefully managed to optimize the acceleration process. When second ions, which have a lower charge-to-mass ratio, are accelerated, the system adjusts the phase difference to enhance performance.
