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


Control Systems


Pyramid devices are modular and pefect for distributed control systems. Easy to use software and networking make prototyping and integration rapid. Pyramid provides long term customer support and high reliability for final production systems.

Our devices can tolerate high levels of HF, RF and transient electrical noise. The real time fiber optic communications between controllers and front-end devices are completely immune to electrical interference. Fiber optics can also span voltage gaps of hundreds of kilovolts. An example application is control of the power supplies in the the high voltage terminal of an accelerator ion source.
