| 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) |
