摘要

A two-dimensional detection system for neutron radiation is disclosed. The detection system includes a means ( 1 ) for emitting a neutron beam ( 10 ), a support means ( 2 ) adapted for receiving a sample ( 3 ), a photoemission means ( 5 ) adapted for being activated by a neutron radiation, and a cooled low light level charge-coupled detection device ( 7 ). The emission means ( 1 ) emits a monochromatic neutron beam ( 10 ). The system further includes a filter means ( 4 ), the filter means ( 4 ) being located between the support means ( 2 ) and the photoemission means ( 5 ) and being adapted for trapping at least a substantial part of the monochromatic neutron beam transmitted ( 12 ) by the sample ( 3 ), and an amplification means ( 6 ) located upstream the charge-coupled detection device ( 7 ) and coupled with the charge-coupled detection device ( 7 ).
