Description

The results of an experimental feasibility study of a position sensitive thermal neutron detector based on a resistive plate chamber (RPC) are presented. The detector prototype features a thin-gap (0.35 mm) hybrid RPC with an aluminium cathode and a float glass anode. The cathode is lined with a 2 μm thick 10B4C neutron converter enriched in 10B. A detection efficiency of 6.2% is measured at the neutron beam (λ = 2.5 Å) for normal incidence. A spatial resolution better than 0.5 mm FWHM is demonstrated.
