Fast neutron detection efficiency of ATLAS-MPX detectors for the evaluation of average neutron energy in mixed radiation fields

Popis výsledku v původním jazyce

Within the framework of the ATLAS-MPX project, the ATLAS-MPX detectors (based on Medipix2 silicon devices) are covered with converting layers of (6)LiF and polyethylene (PE) to make them sensitive to thermal and fast neutrons, respectively. Two ATLAS-MPXreference detectors were exposed to two calibrated neutron sources, (252)Cf (2.2 MeV mean neutron energy) and (241)AmBe (4.08 MeV mean neutron energy), in order to determine their fast neutron detection efficiency. Measurements were performed at low energy threshold (similar to 8 keV) and high energy threshold (similar to 230 keV). Fast neutron detection efficiency is primarily achieved via the use of a 1.3 mm thick polyethylene (PE) converter. Recoil protons from the elastic collision between neutronand hydrogen are detected from their tracks in the 300 mu m thick silicon pixel detector. Calibrated neutron sources were placed at different distances from the detectors, both separately and simultaneously in order to obtain single and s
