摘要
A new collimator for thermal neutrons, based on the honeycomb design, has been produced in a few prototype versions. The method of construction is simple and the overall cost of the device is rather low. Development of this collimator has been stimulated by the technical specifications of the spectrometer BRISP for thermal neutron Brillouin scattering, presently under construction. The performances of the prototypes have been measured on the monochromatic beam of a steady source and exploiting the time-of-flight technique at a pulsed neutron source, The expected response of the device has been calculated by means of a Monte Carlo simulation of the experiments. This paper describes the method of construction and reports on the results of the neutron test measurements in comparison with the Monte Carlo simulation.
