Beam DOWN configuration
Cumulative raw ToF spectra obteined for the case of D2O target and beam DOWN position are presented below:
The width of the photon peak (sigma) shows the IAC linac pulse width at it was mentioned above it was around 2 ns.
Neutron energy spectra reonstructed from the ToF spectra for the beam DOWN and D2O 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.
The energy uncertainty for the beam DOWN and D2O target are shown below:
