Thin-film Strip Detector

Strip detectors have a balance between accuracy on beam position and noise levels. Our strip detectors offer the highest resolution and lowest noise on the market.

  • Laser-machined polyimide electrode substrates
  • Absolute minimal beam scattering
  • Radiation hard
  • High geometric precision
  • Gold plated readout electrodes

Integrated Environment Sensors

Our ion chambers include integrated sensors for environmental corrections. No need for costly and inconvenient external instruments.

  • Humidity sensor
  • Temperature sensor
  • Pressure sesnor
  • Replacable desiccant

Expertly Built

Electrodes patterned with unique laser technology. Assembled and tested by highly skilled technicians in our dedicated assembly facility.

  • Rigorously tested beyond normal operating range to ensure uniformity
  • Envirmonmental sensor measured against externally calibrated sources
  • Each ion chamber is fully retested after it has been opened
  • Real calibrated radioactive source is used as reference
  • Full test documentation can be provided for each individual instrument
