A simple, low-cost ''neutron bang time'' (NBT) detector has been implemented on the OMEGA laser system to measure the average time of neutron emission from inertial confinement fusion targets. This detector uses fast plastic scintillators coupled to photomultiplier tubes. A fast digital real-time oscilloscope records the signals. Absolute timing accuracies of better than 100 ps are achieved over a wide dynamic range (107 < YN < 1011) for both D2 (2.45-MeV) and DT (14-MeV) neutrons using a two-channel setup. Instrument characterization and comparison of the timing accuracy with a streak camera-based neutron burn history diagnostic are presented.
