The INFN-Italy ANET collaboration developed a new design of neutron collimator that should be capable of greatly reducing the distances needed to collimate thermal neutron beams to the levels needed for most neutron inspection analysis and neutron science applications. A typical L/D value of 1000 could be achieved with a 2.5 meter long structure. If successfully tested, the innovating potential of this new collimator design for neutron science is very high. Facilities such as ISIS, ESS SNS, J-PARC would greatly benefit from it. The measurement will consist in the intensity analysis, with respect to the spatial coordinates, of the transmitted neutron signal through a typical elementary cell of this new collimator design.
