摘要
Two new types of luminescent CCD-detectors intended for fast neutron radiography and tomography with a cone neutron beam are described in the paper. A 6 cm thick luminescent screen made of polystyrene is used in the first one to convert fast neutrons. A special optics has been developed to transfer the optical image from the screen to the CCD-matrix. The optics design helps not to loose spatial resolution due to the beam divergence and screen thickness. The second detector is based on the use of a fiber optical screen made of luminescent fibers in the form of a rectangular truncated pyramid. Principles of the detectors operation have been experimentally proved. The obtained results show that the detectors provide a spatial resolution of about 2 mm. (c) 2005 Elsevier B.V.
