Pixelated detectors offer many advantages over strip detectors as they are capable of determining beam shape without ambiguity.

• High precision pixels on gold film provide excellent reliability
• Fine resolution data enable confidence in beam quality
• Compliments the strengths of the gamma index

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

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
