A9 DIAMOND DD-FUSION NEUTRON MONITOR
The DD-Neutron Counter
The Diamond DD-Fusion Neutron Monitor is designed for neutron flux monitoring in fusion reactor applications, where Deuterium-Deuterium Fusion is providing 2.45 MeV neutrons. The detector is optimised for the rejection of γ-background. The Spectroscopic Amplifier allows the installation of a coaxial cable between detector and amplifier for the operation in high-radiation environments.
The A9 is available as remotely controlled Fast-Neutron Monitoring System including ROSY®
with integrated power supply and GUI, for real-time neutron spectroscopy in fusion reactors.

ADDITIONAL PRODUCT INFORMATION
In DD-Fusion Plasma reactors the response function of the Diamond Fast-Neutron Detector is dominated by the elastic scattering of neutrons on the Carbon nuclei. The maximum deposited energy in the diamond sensor is below 1 MeV.
The real-time measurement of the DD-spectrum (Figure) with the ROSY® Readout System is well in accordance with Geant4 simulations.
A threshold of 0.4 MeV will effectively suppress γ-radiation. The neutron count rate can be derived from interactions above this threshold. The neutron detection efficiency can be enhanced by adding additional sensors to the detector.
