10cc Tritium Ion Chamber: 1000 cc & 10 cc ion chamber designs available

---

The 10CC TRITIUM ION CHAMBER's specialized ceramic feed through allows a bias of up to 100V and an anode signal as low as 1 fA (corresponds to 100 µCi/m³ of tritium). When combined with Tyne’s preamplifier and controller package or signal processor this makes an ideal tool for tritium measurement in any process.

• 10cc ion chamber suitable for mCi/m³ to kCi/m³ of Tritium
• Virtual Wall for minimum tritium surface contamination
• Can be used in explosive environment with purge equipment
• Precise, tested and proven 10cc geometry.
• Can bias anode up to 100V from ground
• Inlet precipitator
• Bakeable to cleanse contaminated surfaces from ionization chamber
• Use in a process line or for room air measurements
• Full vacuum to 150 psig
• Flows up to 1 l/s

The 10 cc Ion Chamber is designed to be an in-line radiation in a process gas detector with the most typical application being Tritium. The small volume and the virtual wall technology make this the ideal choice for very high activity measurements. The inlet and outlet VCR 8 connectors allow the chamber to be easily mounted into an existing process line. The internal anode is connected to a floating BNC which can be biased up to 100 V. The high resistance ceramic of the feed through allows the ionization chamber to measure ionization currents as low as 1 fA (1 µCi/m³ of Tritium). The bias voltage is also connected to an inlet precipitator to remove any ionized particles carried into the chamber. The maximum inlet flow rate of 1 L/s ensures that all particles are neutralized before entering the chamber. The ionization chamber is an approved pressure vessel that can handle up to 150 psig, is bakeable up to 350°C and is 1x10E-9 Helium leak tight. 

The ionization chamber is typically connected to Tyne Engineering's preamplifier or signal processor. The preamplifier is a multi-ranged amplifier that connects to a remote controller providing the operator maximum flexibility in measuring the amount of tritium, auto zeroing and alarm functions. The signal processor is a low cost device that provides the bias and converts the 1 fA signal to an easily handled 0 – 10 V signal that can be integrated into any existing data acquisition system.
