Cumulative raw ToF spectra obteined for the case of D2O target and beam up position are presented below:
The width of the photon peak (sigma) shows the IAC linac pulse width which we've been told was around 2 ns.
Neutron energy spectra reonstructed from the ToF spectra are shown below:
The neutron detectors was placed azimuthally symmetric around the target so the distance was 135.5 cm from the center of the target to the face of each of the detector.
The uncertainty on the neutron energy depends mostly on the knowledge of the photon peak center position. The width of the photon peak gives an uncertainty in the neutron energy.
