Time-of-flight measurement of fast neutrons with Timepix detectors

Popis výsledku v původním jazyce

Timepix pixel detectors have been used to study the response of silicon hybrid pixel detectors to fast neutrons from a pulsed neutron beam at WNR FP30R, a 14 m long flight path, in the Los Alamos Neutron Science Center. Neutrons with kinetic energies upto 600 MeV were available. In order to enhance the conversion of neutrons to energetic charged particles, several converter foils and filters were attached to the 300 ?m thick silicon sensor, i.e. polyethylene, polyethylene with aluminum, 6LiF, 6LiF withaluminum, aluminum. The Time-of-Arrival mode of the Timepix detectors has permitted the application of the Time-of-Flight (TOF) technique for the assignment of the detected interactions in the form of clusters (groups of adjacent pixels) in the pixel matrix, to the kinetic energies of the incident neutrons. It was found that, for lower neutron energies (~MeV range) the cluster rates below the polyethylene and the polyethylene and aluminum region, produced by recoil protons, are a good m
