Monochromatic Neutron Tomography Using I-D PSD Detector at Low Flux Research Reactor


This paper describes the monochromatic neutron tomography experiment using the 1-D Position Sensitive Neutron Detector (PSD) located at Nuclear Malaysia TRIGA MARK II Research reactor. Experimental work was perfonned using monochromatic neutron source from beryllium filter and HOPG crystal monochromator. The principal main aim of this experiment was to test the detector efficiency, image reconstruction algorithm and the usage of 0.5 nm monochromatic neutrons for the neutron tomography setup. Other objective includes gathering important parameters and features to characterize the system. Keywords: monochromatic neutron, neutron tomography, Position Sensitive Neutron Detector. N.
