A10 AXIAL - INSTRUMENTED NEUTRON MONITOR
The Instrumented Neutron Probe
The A10 Axial - Instrumented Diamond Neutron Monitor consists of an Axial Detector and a ROSY® real-time readout system with integrated power supply for amplifier and detector bias. The web-based GUI provides real-time neutron spectra and neutron rates for monitoring purposes.
The Axial Detector integrates a spectroscopic diamond detector and a high-temperature Cx-HT Amplifier in one solid stainless-steel housing. The Axial Detector is optimised for fast-neutron monitoring and can be operated up to 175° C.

ADDITIONAL PRODUCT INFORMATION
The measured spectrum of an AmBe fast-neutron source with the A10 Axial - Instrumented Diamond Neutron Monitor at room temperature, 100°C and 175°C shows the temperature stability of the monitor.
The spectrum is dominated by elastic scattering of the neutron on the Carbon nuclei. The 12C(n,α)9Be reaction gives its characteristic distribution.
The rate capability is given by the sensing volume of the detector with about 1% neutron detection efficiency for fast-neutrons.

Schematics of the Axial Detector. The detector comprises a diamond sensor and a high-temperature spectroscopic amplifier, which is to be powered with +12 V.
A low-pass filter is included in the bias line, to suppress potential noise introduced through the bias supply.
The spectroscopic amplifier is AC coupled and has a linear output range of +1 V for a 50 Ω load. The dynamic range corresponds to 20 MeV deposited energy.

Diamond Sensor and integrated spectroscopic amplifier of the A10 Axial Detector are high-temperature compatible and can be operated at ambient temperatures up to 175°C.
The response is stable and well within ±10% in the specified temperature range. This guarantees a reproducible measurement of fast neutrons at elevated temperatures.
