2n Position resolution

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 in: sigma = 5.15 ns and its value converted into cm is 5.15 ns x 7.41 cm/ns = 38.2 cm. The total length of the active area of the neutron detector is 75 cm.
