PHOTONIS Technologies CFUM11 Radiation Detector

Photonis manufactures a broad range of fission chambers for out-of-core use in severe environmental conditions. They are used in thermal neutron detection for up to 11 decades for wide range reactor monitoring.","Description","Their outst Gamma rejection capabilities allow them to be used in waste monitoring applications such as spent fuel monitoring.","Gas filled neutron detectors are designed to operate in three modes. Pulse mode analyzes and counts individual detector pulses. Fluctuation,or Campbell mode,is used to analyze the fluctuation of the direct current from the detector. Current mode is used to measure the mean of the direct current from the detector.","LOCA versions of fission chamber standard models are available on demand. These fission chambers are typically designed with a maximum operating temperature of 250°C (although some versions can monitor up to 600°C) and are equipped with an integrated mineral insulated cable and a HN connector.","Due to the extreme operating conditions of fission chambers,Photonis also recommends the use of a mineral insulated cable extensions designed specifically for the detector.","Main Features

characteristic

• Detecting thermal neutrons over a large flux range
• Extremely safe to use
• Customization according to the user's needs
• Structural form: coaxial or ring.
• Structure material: Aluminum for max. 250°C operational temperature.
• Integrated cable: coaxial mineral insulated cable for pulse and current transmission,high interference immunity. For signals and high voltages operating in harsh environments,integral cables are recommended.
• Connectors: hn mineral insulated connectors for pulse and current transmission.
• Insulators: Since measuring extremely low currents is necessary,insulators must be of very high quality and radiation resistant. photonis only uses high-grade alumina insulators from qualified suppliers.
• Detection of Thermal Neutrons in a Wide Flux Range
• Structural configuration: coaxial or retainer.
• Integral cable: Coaxial mineral insulated cable for pulse and current transmission with high noise immunity. When working in harsh environments,it is recommended to use integrated cables for signal and high voltage.
• Insulators: Due to the need to measure extremely low currents,insulators must be of very high quality and radiation resistance. photonis only uses high-grade aluminum oxide insulators from qualified suppliers.
