The working principle of the SaphyGATE GN is based on the use of 4 to 8 high-volume plastic scintillators installed in each detector. Coupled with fast photomultiplier tubes, the scintillators ensure the detection of Gamma and Neutron radiations.
An electronic unit for prompt processing as well as an algorithm specifically developed for this application allow for the discrimination of Gamma and Neutron radiations from scintillating plastic. The method relies on the analysis of the phenomena occurring within the plastic scintillators in a short period of time (a few nanoseconds).
This patented solution guarantees high detection performances, while performing an efficient Gamma-Neutron discrimination and avoiding Helium-3 supply.
