Angular dependence of two neutron emitted from DU target was determined.
The X-coordinate of the neutron hit of each detector was determined from the TDC difference spectra with application of real calibration factors obtained in separate experiment with Co-60 source.
The timing cuts were applied for TDC sum spectra. It should be noticed that time cuts included both neutron and photon areas because in four fold coincidences the photon accidentals will dissappear.
In the case of Det K it was hard to observe the neutron area and the TDC singles spectra were used to set the time cut (see Det K data on the plot below):
After writing a bunch of scripts the root file was created and the data are plotted below:
In order to see better and distributions it was created a couple of plots with corresponding projections:
