The invention relates to a neutron detector unit for neutrons, in particular thermal and cold neutrons, comprising a detector housing (7, 17, 27), cathode elements and a plurality of anode elements (5, 15, 25), wherein in order to form a volume detector unit the anode elements (5, 15, 25) and the cathode elements enable a three-dimensional spatial resolution for conversion events, characterized by a converter gas in the detector housing (7, 17, 27). According to the invention, in a neutron detector arrangement which includes at least one neutron detector unit the neutron detector unit (3, 13, 23) or at least one of the neutron detector units (3, 13, 23) is oriented in such a way that at least some of the anode elements (5, 15, 25) of the at least one neutron detector unit (3, 13, 23) extend at least predominantly in a longitudinal orientation parallel or almost parallel to the direction of travel of the neutrons (4) to be detected.
A neutron detector unit for thermal and cold neutrons, comprising
A neutron detector arrangement for thermal and cold neutrons comprising at least one neutron detector unit (3, 13, 23) embodied as a volume detector unit, wherein each one of said at least one neutron detector units (3, 13, 23) has a detector housing (7, 17, 27), cathode elements and a plurality of wire-shaped anode elements (5, 15, 25) and wherein a plurality of detector readout cells distributed three-dimensionally in the detector housing (7, 17, 27) are formed, in the at least one neutron detector unit (3, 13, 23), by at least some of said anode elements (5, 15, 25) or by at least some of said anode elements (5, 15, 25) and at least some of said cathode elements for the purposes of determining the position of conversion events, and said neutron detector unit (3, 13, 23) is configured for determining the location by coincidence measurement, charge splitting or determining signal propagation times, wherein said neutron detector unit (3, 13, 23) or at least one of said neutron detector units (3, 13, 23) is aligned in such a way that, in the longitudinal direction thereof, at least some of said anode elements (5, 15, 25) of said at least one neutron detector unit (3, 13, 23) extend, at least predominantly, parallel or almost parallel to the trajectory of the neutrons (4) to be detected.
