Experimental distribution of TDC difference time spectrum (blue) and ideal response function (red) are shown below:
FFT of the signal function and response function is presented below:
Hence, any coordinate of the neutron hit has the following uncertainty: sigma = 5.15 ns and its value converted into cm is 5.15x+/- 37.6 cm. The total length of the active area of the neutron detector is 75 cm.
