As well as neutron detector unit neutron detector array

摘要

It is a neutron detector unit for neutrons, in particular, the thermal and cold neutrons, comprising a detector housing (7, 17, 27), said cathode elements and a plurality of anode elements (5, 15, 25), wherein the anode elements (5, 15, 25) and the cathode elements for the formation of a volume detector unit conversion events allow for a three-dimensional spatial resolution which, by means of a converter gas in the detector housing. (7, 17, 27) is characterized. In the case of an at least one having neutron detector unit neutron detector array, it is proposed that the neutron detector unit (3, 13, 23) or at least one of the neutron detector units (3, 13, 23) to be aligned in such a way that at least a partial number of the anode elements (5, 15, 25) of the at least one neutron detector unit (3, 13, 23) of at least predominantly in their longitudinal orientation parallel or almost parallel to the flight direction of the neutrons to be detected (4) runs.
