DETECTOR, METHOD FOR MANUFACTURING A DETECTOR AND IMAGING APPARATUS

摘要

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. The thickness of the first semiconductor element (101) is adapted to be electrically and/or physically so thin that it is essentially/practically transparent for incident photons, such as background gamma photons.
