Neutron Flux Characterization of the Cold Beam PGAA-NIPS Facility at the Budapest Research Reactor

摘要

Reliable flux characterization is essential for facilities using neutron beams. Hence, the NIPS station at the Budapest Research Reactor has recently been equipped with neutron-tomographic equipment. The beam can also be characterized by means of a large surface wire chamber and application of the time-of-flight method. The energy distribution was measured at three horizontal positions with the surface wire chamber in pinhole geometry, while the spatial inhomogencity was determined by means of our new neutron-tomographic equipment.
