Detector for thermal neutrons utilizing alternating boron slabs and CCD arrays

摘要

A detector for thermal neutrons comprising a stack of alternatingly arranged boron slabs and CCD arrays. The CCD arrays are receptive to energetic particles generated in the boron slabs by a thermal neutron, which energetic particles escape the boron slab in which they are generated and are captured by the next-adjacent CCD array, the CCD array being provided with circuit and power means to operate it and to read out the charges developed in the CCD arrays. The boron slabs are sufficiently thin that the energetic charged particles can escape, and the CCD arrays are sufficiently thick that the energetic particles will be trapped by them, and a charge will be developed therein which will be detected and measured.
