Scattered protons 1443000100015 were detected using Faraday cup. The time dependence of1443000100016 the Faraday cup current is a measure of the energy 1443000100017 spectrum of the neutrons that leak from the device. 1443000100018 METHOD (TOF) 1443000100019 INC-SOURCE (EXPLO) Underground nuclear explosions conducted at 1443000100020 the Nevada Test Site 1443000100021 ERR-ANALYS (ERR-T) Total uncertainty 1443000100022 (ERR-1) Uncertainty in NUEX currents 1443000100023 (ERR-2) Uncertainty in cross sections and geometry 1443000100024 (ERR-3) Uncertainty in contribution of non H ions 1443000100025 (ERR-4) Uncertainty in fusion peak shape 1443000100026 (ERR-5) Uncertainty in fusion peak size 1443000100027 (ERR-6) Uncertainty in fusion peak timing 1443000100028 (ERR-7) Uncertainty in fusion peak Monte Carlo 1443000100029 (ERR-8) Uncertainty in correction for 14 MeV neutrons 1443000100030 HISTORY (20150729C) Compiled by S.H. 1443000100031 ENDBIB 29 0 1443000100032 COMMON 1 3 1443000100033 EN 1443000100034 MEV 1443000100035 1.5 1443000100036 ENDCOMMON 3 0 1443000100037 ENDSUBENT 36 0 1443000199999 SUBENT 14430002 20150729 14091443000200001 BIB 2 2 1443000200002 REACTION (94-PU-239(N,F),PR,NU/DE) 1443000200003 STATUS (TABLE) Data taken from tabs. 1 and 3 of the LA report 1443000200004 ENDBIB 2 0 1443000200005 NOCOMMON 0 0 1443000200006 DATA 11 11 1443000200007 E DATA ERR-T ERR-1 ERR-2 ERR-3 1443000200008 ERR-4 ERR-5 ERR-6 ERR-7 ERR-8 1443000200009 MEV PT/FIS/MEV PT/FIS/MEV PER-CENT PER-CENT PER-CENT 1443000200010 PER-CENT PER-CENT PER-CENT PER-CENT PER-CENT 1443000200011 1.5 0.2905 0.0073 0.6 2.0 1443000200012 1.2 1443000200013 2.5 0.1945 0.0049 0.6 2.0 1443000200014 1.2 1443000200015 3.5 0.1110 0.0028 0.6 2.0 1443000200016 0.1 0.2 0.1 1.3 1443000200017 4.5 0.0607 0.0015 0.6 2.0 1443000200018 0.1 0.4 0.1 1.4 1443000200019 5.5 0.0318 0.0010 0.6 2.0 0.1 1443000200020 0.1 0.1 0.8 0.1 1.9 1443000200021 6.5 0.0166 0.0006 0.6 2.0 0.3 1443000200022 0.1 0.2 1.2 0.2 2.5 1443000200023 7.5 0.00853 0.00039 0.8 2.0 0.9 1443000200024 0.2 0.4 1.6 0.5 3.6 1443000200025 8.5 0.00421 0.00035 2.7 2.0 1443000200026 1.1 1.1 5.1 1.3 5.1 1443000200027 9.5 0.00224 0.00026 4.0 2.0 1443000200028 3.2 2.2 6.9 2.6 6.8 1443000200029 10.5 0.00135 0.00027 7.4 2.0 1443000200030 11.2 5.6 8.5 5.1 8.6 1443000200031 11.5 0.00029 0.00032 33.0 2.0 1443000200032 98.0 30.0 10.5 26.0 10.7 1443000200033 ENDDATA 26 0 1443000200034 ENDSUBENT 33 0 1443000299999 SUBENT 14430003 20150729 14091443000300001 BIB 2 2 1443000300002 REACTION (92-U-235(N,F),PR,NU/DE) 1443000300003 STATUS (TABLE) Data taken from tabs. 2 and 4 of the LA report 1443000300004 ENDBIB 2 0 1443000300005 NOCOMMON 0 0 1443000300006 DATA 11 9 1443000300007 E DATA ERR-T ERR-1 ERR-2 ERR-3 1443000300008 ERR-4 ERR-5 ERR-6 ERR-7 ERR-8 1443000300009 MEV PT/FIS/MEV PT/FIS/MEV PER-CENT PER-CENT PER-CENT 1443000300010 PER-CENT PER-CENT PER-CENT PER-CENT PER-CENT 1443000300011 1.5 0.2947 0.0074 0.8 2.0 1443000300012 1.3 1443000300013 2.5 0.1884 0.0047 0.8 2.0 1443000300014 1.2 1443000300015 3.5 0.1063 0.0028 0.8 2.0 1443000300016 0.1 0.1 0.1 1.4 1443000300017 4.5 0.0559 0.0015 0.8 2.0 1443000300018 0.8 0.1 0.4 0.1 1.3 1443000300019 5.5 0.0277 0.0011 0.8 2.0 0.1 1443000300020 2.9 0.1 0.8 0.1 1.1 1443000300021 6.5 0.0144 0.0007 0.8 2.0 0.4 1443000300022 3.6 0.2 1.2 0.2 1.6 1443000300023 7.5 0.00638 0.00071 1.0 2.0 1.2 1443000300024 10.3 0.5 1.6 0.6 2.6 1443000300025 8.5 0.00292 0.00061 1.2 2.0 3.0 1443000300026 20.0 0.5 2.2 1.1 4.1 1443000300027 9.5 0.00091 0.00061 1.8 2.0 7.0 1443000300028 66.0 1.0 2.7 2.3 5.8 1443000300029 ENDDATA 22 0 1443000300030 ENDSUBENT 29 0 1443000399999 ENDENTRY 3 0 1443099999999
