The proton beam facilities at Mayo Clinic in Rochester, Minnesota, and Phoenix/Scottsdale, Arizona, each house their own particle accelerator that drives protons to nearly the speed of light before delivering therapeutic radiation to your tumor.
Four treatment rooms at each facility
Each facility has four proton beam treatment rooms equipped with pencil beam scanning that operate about 12 hours a day. That means you receive treatment as quickly and as efficiently as possible.
Proton Beam Therapy Program — Mayo Clinic's campus in Arizona
The proton beam therapy facility is located east of the Mayo Clinic Specialty Building on the Phoenix campus.
Proton Beam Therapy Program — Mayo Clinic's campus in Minnesota
The proton beam therapy facility in Minnesota is located in downtown Rochester on the Mayo Clinic campus, just northeast of Mayo Clinic Hospital, Methodist Campus (the corner of Second Street Northwest and First Avenue Northwest), in the Jacobson Building.
The Jacobson Building is connected to other campus buildings by an underground walkway (subway) and skyway system, so you can get to other appointments, hotels, restaurants and shopping without ever going outside.
The building is named in honor of Richard Jacobson, a grateful patient, in recognition of his transformative gift to Mayo Clinic.
