Abstract |
In this work, we have developed and characterized a position-sensitive CLYC detector that acts as the neutron imaging layer and y-ray Compton scatterer of the novel dual Gamma-ray and Neutron Vision (GN-Vision) system, which aims at simultaneously obtaining information about the spatial origin of y-ray and neutron sources. We first investigated the performance of two large 50 x 50 mm2 monolithic CLYC crystals, 8 and 13 mm thick respectively, coupled to a pixelated SiPM in terms of energy resolution and neutron-gamma discrimination. The response of two different 95% 6Li-enriched CLYC detectors coupled to an array of 8 x 8 SiPMs was studied in comparison to the results of a conventional photo-multiplier tube. An energy resolution of about 6% with PMT and 8% with SiPMs for the 137Cs peak and a figure of merit of 3-4 for the neutron-gamma discrimination have been obtained. The spatial response of the CLYC-SiPM detector to y-rays and neutrons has also been characterized using charge modulation-based multiplexing techniques based on a diode-coupled charge division circuit. Average resolutions close to 5 mm FWHM with good linearity are obtained in the transverse crystal plane. Last, this work presents the first proof-of-concept experiments of the neutron imaging capability using a neutron pinhole collimator attached to the developed position sensitive CLYC detector. |
