-==Target in vs. target out==
-Gamma peak is revealed by comparing target in and target out runs.

-==ToF==
-<math>Neutron TOF=\frac{PMT_{top}+PMT_{bottom}}{2}-t_{\gamma peak}+\gamma_{TOF}</math>

-==Energy==
-Neutron Energy:
-<math>\frac{1}{2}m_{n}\left(\frac{in}{ns}\right)^2=3.372\left(\frac{42}{t}\right)^2 MeV</math>
-Watt distribution:
-<math>Ce^{-aE^'}\sinh\left(\sqrt{bE^'}\right)=0.708 e^{-0.884 E^'}\sinh \left(\sqrt{E^'}\right)</math>

-==Opening angles==
-Uncorrelated distribution from detectors 1-4:
-[[File:Snip20150729 3.png|750 px]]
-Analyzing 5653446 pulses from DU runs, I was able to find 349 two-neutron events in detectors 1-4.

-As a test I did the same for gamma events:
