摘要：

A measuring device for large angle coincidence neutron depth profiling was installed behind a 5.6 m long neutron guide. Two large area PIN diodes placed at a distance of 2 mm from the sample serve for the detection of particles emitted at different angles. Coincidence event registration and sorting was accomplished using a PC AT computer. A simple but effective technique for two-dimensional data evaluation is proposed. The feasibility of the method was tested on various standards. The detection limits and the depth resolution are determined and possible refinements of the technique are discussed.
