The paper was aimed to compare performance capabilities of two types of scintillation detectors commonly used for fast neutron imaging: two dimensional and linear ones. Best-case values of quantum efficiency, spatial resolution and capacity were estimated for detectors with plastic converter-screen in case of 14 MeV neutrons. For that there were examined nuclear reactions produced in converter-screen by fast neutrons, spatial distributions of energy release of emerged charged particles and amplitude distributions of scintillations generated by these particles. The paper shows that the efficiency of the linear detector is essentially higher and this detector provides potentially better spatial resolution in comparison with the two dimensional detector. But, the two dimensional detector surpasses the linear one in capacity. The presented results can be used for designing radiographic fast neutron detectors with organic scintillators.

“…A promising way for designing a large area radiographic detector is the application of the socalled matrix screen, in particular, a fiber screen [4]. In general, the matrix screen is a honeycomb structure with light reflecting walls and cells filled with a scintillator.…”

Proton beam characterisation of a prototype thin-tile plastic scintillator detector with SiPM readout for use in fastneutron tracker R Preston, J Jakubek, D Prokopovich et al. ABSTRACT: The paper analyses the factors affecting the detection efficiency and the spatial resolution of the luminescent detectors intended for fast neutron imaging. An analytical approach has been used for this purpose. A design of the large area detector based on the application of a matrix screen and a set of crossed wavelength shifting fibers (WLS) for reading out the scintillation signal has been suggested. The spatial resolution of the detector depends on the cross section of the matrix cell. The detection efficiency of the detector is sufficiently high and can amount to about 25% for the screen made of polyvinyl toluene in the case of 14 MeV neutrons.
