Neutron detector unit and neutron detector array

It is a neutron detector unit for neutrons, particularly thermal and cold neutrons, presented comprising a detector housing (7, 17, 27), cathode elements and a plurality of anode elements (5, 15, 25), wherein the anode members (5, 15, 25) and the cathode elements to form a detector unit volume allowing a three-dimensional spatial resolution for converting events represented by a converter gas within the detector housing. (7, 17, 27) is characterized. In one at least one neutron detector unit having neutron detector array is proposed that the neutron detector unit (3, 13, 23) or at least one of the neutron detector units (23 3, 13) aligned such that at least a partial number of anode elements (5, 15, 25) of at least one neutron detector unit (3, 13, 23) at least predominantly parallel or nearly parallel to the direction of flight of the neutrons to be detected (4) in their longitudinal orientation.
