Abstract:
Two economic and practical resin-dipped boron coating methods for neutron detectors were presented, whose names are dip coated boron deposition (DCBD) and hand painted boron deposition (HPBD). Several experiments on stainless steel sheet show that the minimum of the resin-boron ratio
λ in DCBD is 5.0, while the best value of λ in HPBD is 0.2. The better method is that the mixture drops on the coated surface firstly, and then the boron powder is scattered by hand. Finally, a cylindrical boron lined proportional counter made by using this method was irradiated by a standard Am-Be neutron source, and the output pulses were measured. After the proportional counter was wrapped by PE tubes with different thickness, the neutron spectra of the Am-Be source were measured. By analyzing the parameters of the neutron spectra, it is found that these two manufacture crafts have a simple and feasible process, which would provide the coworkers with meaningful reference.
