Runs 4111(D2O)/4112(H2O)

Subtraction of the stops for each detector in the case of D2O target. The length of the active area (scintillator) of the detector is 75.3 cm.

Subtraction of the stops for each detector in the case of H2O target:

Normalized superimposed timing spectra from D2O(black line)/H2O(red line) targets and bin-by-bin subtraction (green line) of D2O-H2O data:

Errors on the neutron energy for the case of Det M:

[math]E_n \pm U(E_n)=mc^2/2 \cdot 1/c^2 \cdot (l_n/t_n)^2 \cdot [1 \pm 2 \sqrt{U^2(l_n)/l^2_n + U^2(t_n)/t^2_n}][/math]

Where [math]U(l_n) = 14.8/2 \cdot cos(\theta)[/math] and [math]U(t_n)=10 ns[/math]
