FFT algorithm test
If we take narrower response function we will get
FFT application
Experimental distribution of TDC difference time spectrum (blue) and ideal response function (red) are shown below:
Hence, any coordinate of the neutron hit has the following uncertainty in: sigma = 1.5 ns and its value converted into cm is 1.5 ns x 7.24 cm/ns = 10.8 cm. The total length of the active area of the neutron detector is 75 cm.
