AbstraktAbstract
The ATLAS-MPX detectors are based on Medipix2 devices covered with converting layers of 6LiF and polyethylene (PE) to increase their sensitivity to thermal and fast neutrons. The signature of particles interacting in a ATLAS-MPX detector are clusters of adjacent pixels with different size and form depending on their type, energy and incidence angle.The Medipix analysis framework (MAFalda) (based on the ROOT application) allows classification of particles into different categories using the geometrical parameters of the clusters. The pattern recognition obtained from the application of MAFalda was configured to distinguish the response of neutrons from other radiation. The neutron detection efficiency of ATLAS-MPX devices has been determined by the exposure of two detectors of reference to radionuclide sources of neutrons (252Cf and 241AmBe). With these results, an estimate of the neutrons fields produced at the devices locations during ATLAS operation was done.
