Description/Abstract:
THIS REPORT DEALS WITH THE NEUTRON MEASUREMENTS PERFORMED BY THE NAVAL RESEARCH LABORATORY-HALL GROUP ON [ ] STUDIED IN O PERATION GREENHOUSE. THE OBJECT OF THE TENEX EXPERIMENT WAS TO DISPLA Y THE NUMBER-VELOCITY DISTRIBUTION OF THE BURST OF 14-MEV NEUTRONS EXP ECTED FROM A TEMPERATURE-INDUCED NUCLEAR REACTION BETWEEN DEUTERIUM AN D TRITIUM. THE OBJECT OF THE TIME-OF-FLIGHT EXPERIMENT WAS TO DISPLAY THE NUMBER-VELOCITY DISTRIBUTION OF THE HIGH-ENERGY PORTIONS OF THE N EUTRON SPECTRA LYING BELOW 14 MEV AND ORIGINATING IN THE FISSION REACT IONS. IN EACH CASE THE TIME OF FLIGHT OF THE NEUTRON TO THE DETECTOR WAS USED TO MEASURE THE VELOCITY AND HENCE THE ENERGY OF THE NEUTRONS. HYDROGENOUS SCINTILLATING FLUORS, VIEWED BY PHOTOSENSITIVE CELLS AND SHIELDED FROM GAMMA RAYS BY LEAD, WERE USED AS DETECTORS. THE PULSES WERE DISPLAYED ON BANKS OF CATHODE-RAY SYNCHROSCOPES AND PHOTOGRAPHED . NEGLECT OF THE EFFECTS OF POSSIBLE NONEQUILIBRIUM CONDITIONS DURING THE FUSION REACTION, OF THE DURATION OF THE REACTION, AND OF THE INTE RACTION BETWEEN THE D-T NEUTRONS AND MATTER IN THEIR PASSAGE TO THE DE TECTOR MAY HAVE CAUSED THE ABOVE-STATED VALUES OF REACTION ENERGIES AN D TEMPERATURES TO BE TOO LARGE.
