Detector, method for manufacturing a detector and imaging apparatus

Abstract

A detector ( 100 ) for detecting neutrons comprises a neutron reactive material ( 102 ) adapted to interact with neutrons to be detected and release ionizing radiation reaction products in relation to said interactions with neutrons. The detector also comprises a first semiconductor element ( 101 ) being coupled with said neutron reactive material ( 102 ) and adapted to interact with said ionizing radiation reaction products and provide electrical charges proportional to the energy of said ionizing radiation reaction products. In addition electrodes are arranged in connection with said first semiconductor element ( 101 ) for providing charge collecting areas ( 106 ) for collecting the electrical charges and to provide electrically readable signal proportional to said collected electrical charges. In the detector ( 100 ) the neutron reactive material is arranged so that the incident neutrons to be detected interact with the neutron reactive material ( 102 ) essentially in the portion nearest to said charge collecting areas ( 106, 110 ) provided by the electrodes in said first semiconductor element ( 101 ) to which said neutron reactive material is coupled with.

1 . A detector for detecting neutrons, wherein the detector comprises:
 a neutron reactive material for interacting with neutrons incident thereon to be detected to release ionizing radiation reaction products responsive to interactions with the incident neutrons,   a first semiconductor element arranged to interact with the ionizing radiation reaction products for providing electrical charges in proportion to the energy of said ionizing radiation reaction products,   wherein the first semiconductor element is configured with electrodes for providing charge collection areas for collecting the electrical charges and to provide electrically readable signals proportional to said collected electrical charges, and wherein the neutron reactive material is arranged in the detector substantially on the same side of the first semiconducting element as the electrodes.
