Beam Transport System The Beam Transport System guides the 70-250 MeV proton beam from the accelerator to one of the many treatment rooms at the facility. (The accelerator and beam transport system are capable of delivering beams much lower than 70MeV under research environments.) The beam transport system consists of several bending and focusing magnets, which maintain the beam's intensity and position. Beam position monitors maintain the size, position, and intensity of the beam's path. Vacuum pumps and monitors, as well as other diagnostic and control devices, ensure correct beam parameters for patient treatment. If these devices detect variations from the prescribed beam parameters, the control system adjusts the beam, or trips the safety interlock, which automatically disables beam delivery. Depending on the treatment, the beam is routed to the fixed beamline (for patients with head, eye, or similar cancers), or one of the isocentric gantries (for patients with other forms of cancer).
