Facility LayoutThe Loma Linda University Medical Center Proton Treatment CenterStationary Beam:
Has two branches: •Eye Tumors •Head and Neck Tumors
The Injector:Protons are stripped out of the nucleus of hydrogen atoms and sent to the accelerator.
Synchrotron: (Accelerator)A ring of magnets, 20 ft. in diameter, through which protons circulate in a vacuum tube.
Beam Transport System:Carries the beam from the accelerator to one of four treatment rooms. This system consists of several bending and focusing magnets which guide the beam around corners and focus it to the desired location.
The Gantries:Resembling giant ferris wheels can rotate around the patient and direct the proton beam to a precise point. Each gantry weights about 90 tons and stands 3 stories tall. It supports the bending and focusing magnets to direct the beam.
Steel-reinforced concrete walls are up to 15 feet thick.
