Abstract: Resistive plate chambers (RPC) lined with 10B4C neutron converters is a promisingcost-effective technology for position-sensitive thermal neutron detection capable to outperform3He-based detectors in terms of spatial resolution and timing. However, as for the other types ofgaseous detectors with a single layer of 10B4C at normal beam incidence, the detection efficiency tothermal neutrons of a single-gap 10B-RPC is only about 6%. Aiming to overcome this limitation,we introduce a multi-layer 10B-RPCs detector with a stack of ten double-gap hybrid RPCs. Adescription of the detector design and the results of its characterization performed at the TREFFneutron beamline at the FRM II neutron facility are presented. The results demonstrate that thedetection efficiency exceeds 60% for neutrons with a wavelength of 4.7Å and the spatial resolution(FWHM) is about 0.25mm and 0.35mm in the X and Y direction, respectively.
