Abstract:
To perform cosmic muons flux measurements and reconstruct each event incident trajectory we had built a detector based on plastic scintillators, optical fibers (wavelength shifters) and readout by SiPM(MPPC-Multi Pixel Photon counter) devices.
The detector is consisting of a stack of 6 active modules, grouped in 3 layers for determining the muon trajectories through 3 planes. One module has 24 plastic scintillators stripes with 2 fibers mounted on each stripe, readout by 24 MPPC devices. The active surface is 1m x 1m.
The acquisition system was built in such manner that each event trajectory can be seen on screen in real time.The detector can be used to measure muon flux at ground level or in the underground (low radiation background) for studying the possibility to detect unknown cavities or to explore variations in the rock density and composition above the observation level for non-invasive geological studies.
