  • Automated purge and sustain modes
  • Monitors helium inlet pressure
  • Remote sensor unit close to helium chamber
  • Monitors residual oxygen, pressure, temperature and orientation
  • Logging of helium consumption
  • Pressure control servo mode
  • Compatible with Pyramid nozzle helium chambers


  • Control of helium beampaths in proton therapy nozzles
  • Maintains helium level to minimise beam scattering
  • Applications requiring flow or pressure control close to atmospheric pressure

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
