Muon Telescope Data

Experimental Set Up

Smaller top and bottom scintillators were used (width: 1.0 cm, height: 1.9 cm, length: 4.5 cm) in the hopes of determining an attenuation coefficient of light in the scintillator. The coincidence cross section was set up to be 1.5 cm centered along the diameter of the sample and 1 cm down the length of the sample, as shown in Figure 1.
