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 .
