Pyramid offers high speed scanning magnets and Hall probes suitable for pencil beam scanning proton therapy systems. We are experienced at implementing the control systems for particle accelerators and their beamlines. Our devices are proven in the accelerator beamline environments.

Pyramid is pleased to work with FMB-Oxford Ltd to supply products to the international synchrotron light source beamline community.

Proton Therapy

Proton therapy is well established for the treatment of localized cancer tumors, especially when there are vital organs close by. This healthy tissue sparing makes it the method of choice for maintaining quality of life and especially for treating children. The proton beam delivery is fast and painless.

Proton therapy centers worldwide use Pyramid sensors, electronics, and software. Pyramid offers products for complete systems, sub-systems, or components. For more information see our Pencil Beam Scanning Brochure
