Facility Layout
The Loma Linda University Medical Center Proton Treatment Center
The Gantries:
Has two branches: •Eye Tumors •Head and Neck 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 Tumors stands 3 stories tall. It supports the bending and focusing magnets to direct the beam.
The Injector:
Protons are stripped out of the nucleus of hydrogen atoms and sent to the accelerator.
Steel reinforced concrete walls are up to 15 feet thick.
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 corners and focus it to the desired location .
