| 520 | _ | _ | |a Research on novel approaches concerning scintillation based solid-state detectors to be used in small angle neutron scattering (SANS) experiments [1] has been triggered through low world-wide availability of the 3He gas [2], which has been the detection material of choice for most neutron detection tasks. The active area sizes of such detectors might vary between 1 m² (sometimes smaller) and 30 m² or more, depending on the instrument design. It is reasonable to stress the enormous readout and data rate concerned complexities accompanying a pixelated solid-state approach for SANS scintillator detectors, if a single “pixel” size of some mm² is considered in neutron detectors with active areas of several tens of square meters. Nevertheless, in SANS instruments requiring active areas up to 1 m², the approach based on an indirect detection of impinging cold and thermal neutrons via pixelated scintillator detectors, where the size of each “pixel” would be defined only by the dispersion of visible photons produced within the overlying scintillator material, this approach becomes feasible. An interesting candidate for the photodetector part in these detectors could be an array of analog silicon photomultipliers (SiPM). It would yield the possibility of single photon counting, low power consumption, a space resolution of at least 3×3 mm² (or less), and the possibility of acceptable photodetection performance even in presence of high magnetic fields. The main risk defined so far for using this technology in SANS scintillation detectors is their performance in hard radiation environments: in this case, under the irradiation of thermal or cold neutrons. We investigated the dark signal and breakdown voltage performances of a 12x12 array of SensL Series C SiPMs with an active area of 3x3 mm² under irradiation with cold neutrons (lambda = 5 Å, and the main neutron flux of 108 n·s-1cm-2) up to a dose of 2×1012 n·cm-2. The SiPM detectors were at all times fully operational, and the measurements were performed in-situ.[1] D. L. Price and K.
