Trajectory determination of muons using scintillators and a novel self-organizative map
In this work we propose a method for the determination of the impact point of muons in scintillators using a novel type of self-organizative maps called Self-Equalizing Map (SEM) and comparing the relative pulse height obtained by four photomultipliers (PMTs) at each scintillator. Using two 1 m${^2}...

Summary: | In this work we propose a method for the determination of the impact point of muons in scintillators using a novel type of self-organizative maps called Self-Equalizing Map (SEM) and comparing the relative pulse height obtained by four photomultipliers (PMTs) at each scintillator. Using two 1 m${^2}$ scintillators and calculating the impact point in both of them, we can also estimate the angle of incidence of these particles. This method has been specifically designed for a muon telescope called MITO (Muon Impact Tracer and Observer) which is part of the ORCA (Antarctic Cosmic Ray Observatory). Data from tests using MITO in Livingston Island, Antarctica have been used to evaluate the feasibility of this method. The obtained directions have been found to be consistent with the expected incident directions of atmospheric muons produced by the interaction between CRs and atmospheric atoms.
