Experimental distribution of TDC difference time spectrum (blue) and ideal response function (red) are shown below:
Raw data of FFT deconvolution of signal function and response function is presented below:
It can be seen the high frequency noise component in the raw data. Applying low pass filtering we could get the deconvoluted data:
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.
