	A test was performed using a Cf-252 source and two plastic scintillator detectors. The two detectors were placed in parallel with the source. The idea was that the source would emit a neutron and that neutron would hit the first detector and then the second. The signals from the detectors would show up on the oscilloscope being spaced a certain measurable distance/time apart. This was acquired by gating the signal.
