The 1457500100018 vessel has a form of truncated cone with overall 1457500100019 length of 7.5cm, smallest diameter of 0.9cm and 1457500100020 largest diameter of 4cm. The nuclear reaction vessel 1457500100021 was positioned 9cm from the center of the OMEGA 1457500100022 target chamber. 1457500100023 DETECTOR (SCIN) Neutrons were detected using liquid 1457500100024 scintillation detector filled in cylindrical cell 1457500100025 with diameter of 20 cm and depth of 10 cm. Cell was 1457500100026 filled with scintillator based on oxygenated xylene 1457500100027 doped with diphenyl oxazole C15H11NO+ p-bis-(o- 1457500100028 methylstyryl)-benzene (PPO+ bis-MSB) wavelength- 1457500100029 shifting dyes, which scintillates and emits light in 1457500100030 the visible to near-ultraviolet wavelength range (380 1457500100031 to 420 nm) . This oxygenated liquid scintillator has 1457500100032 a fast time response and a low-light afterglow. 1457500100033 Scintillator was read out by four microchannel-plate 1457500100034 photomultiplier tubes. The ports for the MCP-PMT are 1457500100035 40-mm-diam fused-silica windows mounted on the 1457500100036 cylindrical cell and sealed with Viton O rings. 1457500100037 METHOD (TOF) Neutron detector was positioned stance of 13.4m 1457500100038 from target chamber. 1457500100039 INC-SOURCE (D-T) Neutrons are generated using a laser to implode 1457500100040 thin-walled micro balloons with thickness of approx. 4.1457500100041 mu-m and diameter of cca 1mm filled with 10 atm of 1457500100042 D-T fuel. The OMEGA UV has 60 laser beams which 1457500100043 deliver up to 30 kJ of energy onto the D-T target 1457500100044 during a nominal 1-ns square pulse. The shock wave 1457500100045 caused by laser pulse compresses and heats the fuel 1457500100046 as it converges at the center of the target. The fuel 1457500100047 reaches sufficient temperatures to produce 1457500100048 thermonuclear reactions with neutron yields of up to 1457500100049 1E+14 neutrons emitted into 4Pi. The neutron emitting 1457500100050 region is approx.. 100 mu-m in diameter and 100 ps 1457500100051 duration. 1457500100052 ANALYSIS Separate experiments were performed with 1457500100053 deuterated samples D2O,C6D6 and nondeuterated targets 1457500100054 H2O,C6H6. The neutron yield from deuteron breakup 1457500100055 contribution was extracted from difference in time of 1457500100056 flight spectra obtained from deuterated and 1457500100057 nondeuterated targets. The primary D-T signal from 1457500100058 monitor diagnostic was used to normalize both time of 1457500100059 flight spectra. 1457500100060 ERR-ANALYS (ERR-S) Statistical uncertainty 1457500100061 (ERR-SYS) Systematic uncertainty 1457500100062 (ERR-T) Total uncertainty 1457500100063 HISTORY (20191008C) Compiled by S.H. 1457500100064 ENDBIB 62 0 1457500100065 COMMON 5 3 1457500100066 EN ANG-MIN ANG-MAX ERR-S ERR-SYS 1457500100067 MEV ADEG ADEG PER-CENT PER-CENT 1457500100068 14.0 0. 7.4 3. 9. 1457500100069 ENDCOMMON 3 0 1457500100070 ENDSUBENT 69 0 1457500199999 SUBENT 14575002 20191008 14601457500200001 BIB 3 4 1457500200002 REACTION (1-H-2(N,2N)1-H-1,,DA/DE) 1457500200003 STATUS (TABLE) Data taken from tab. 1 of the reference 1457500200004 (COREL,14575003) Result from C6D6 sample 1457500200005 SAMPLE D2O Deuterated water 1457500200006 ENDBIB 4 0 1457500200007 NOCOMMON 0 0 1457500200008 DATA 3 17 1457500200009 E DATA ERR-T 1457500200010 MEV MB/SR/MEV MB/SR/MEV 1457500200011 1.22 1.42 1.98 1457500200012 1.74 4.85 1.50 1457500200013 3.26 5.80 1.88 1457500200014 3.77 9.26 1.80 1457500200015 4.27 11.93 2.00 1457500200016 4.78 14.21 1.91 1457500200017 5.28 14.39 1.86 1457500200018 5.78 12.99 1.78 1457500200019 6.29 13.14 1.97 1457500200020 6.79 11.02 1.47 1457500200021 7.30 10.58 1.30 1457500200022 7.80 10.22 1.08 1457500200023 8.30 8.65 1.15 1457500200024 8.81 7.59 2.67 1457500200025 9.31 8.16 1.02 1457500200026 9.81 6.80 3.43 1457500200027 10.32 4.60 0.86 1457500200028 ENDDATA 19 0 1457500200029 ENDSUBENT 28 0 1457500299999 SUBENT 14575003 20191008 14601457500300001 BIB 3 4 1457500300002 REACTION (1-H-2(N,2N)1-H-1,,DA/DE) 1457500300003 STATUS (TABLE) Data taken from tab. 1 of the reference 1457500300004 (COREL,14575002) Result from D2O sample 1457500300005 SAMPLE C6D6 1457500300006 ENDBIB 4 0 1457500300007 NOCOMMON 0 0 1457500300008 DATA 3 18 1457500300009 E DATA ERR-T 1457500300010 MEV MB/SR/MEV MB/SR/MEV 1457500300011 0.70 2.69 6.67 1457500300012 1.22 3.43 3.00 1457500300013 1.74 1.44 1.73 1457500300014 3.26 5.24 0.88 1457500300015 3.77 6.27 1.94 1457500300016 4.27 9.73 1.76 1457500300017 4.78 13.24 1.73 1457500300018 5.28 15.46 1.93 1457500300019 5.78 15.12 1.56 1457500300020 6.29 13.48 1.82 1457500300021 6.79 12.52 1.48 1457500300022 7.30 10.41 1.72 1457500300023 7.80 8.28 1.42 1457500300024 8.30 8.34 1.13 1457500300025 8.81 7.40 1.56 1457500300026 9.31 4.74 6.01 1457500300027 9.81 5.74 1.74 1457500300028 10.32 5.76 3.66 1457500300029 ENDDATA 20 0 1457500300030 ENDSUBENT 29 0 1457500399999 ENDENTRY 3 0 1457599999999
