Protons are produced from hydrogen gas in an ion source, and are accelerated in a linear accelerator.
After being accelerated in a linear accelerator, protons are then sent to a ring accelerator (synchrotron) and are accelerated at the speed of which they could travel around the earth 4 times in just one second.
Protons accelerated up to have enough energy for the therapy now become a proton beam. While the beam travels inside a vacuum pipe, it is refracted by the effects of electromagnets and goes into each irradiation room.
The proton irradiator targets the tumor only, widening the beam in three dimensions (length, width and depth) accurately in accordance with the cancer volume.
