DU runs
TDC spectrum
Detector 1
Detector 2
Detector 3
Detector 4
Target in vs. target out
Gamma peak is revealed by comparing target in and target out runs.

Neutron Energy:
Watt distribution:
Second Hit
Odd TDC spectrum in the second hit:
Applying cuts based on TDC difference could help:
Opening angles
Uncorrelated distribution from detectors 1-4:
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:
