Time spectra measured between the reference and receiver detectors. They were measured for different given distances of 1.8 m (blue circles), 2.4 m (orange circles), and 3.0 m (gray circles) (a). The error bars show the standard deviation. Accuracy in the distance calculation as a function of the number of events (b). The inset shows the TOF spectra for different accumulation numbers: 10 muons, 70 muons, 140 muons, and 700 muons. The horizontal axis was converted to the distance by multiplying the speed of light in a vacuum.
