Figures

Run 6714 and 6715	Run 6738 and 6741, trigger required hit in both gamma detectors and at least one neutron detector. Detector in TDC channel 12 is 2.5 meters away from source while Detector 8 (in runs 6714 and 6715) is 1.25 meters away	Run 6741 and 6756 Added 2" of lead to front of neutron scintillator and moved TDC to less noisy NIM-ECL channe (channel 12 -> channel 10)
