It is a 60-terawatt, 60-beam, frequency- C256900100011 tripled Nd:glass laser system designed to perform C256900100012 precision direct-drive inertial-confinement-fusion C256900100013 experiments. C256900100014 SAMPLE Spherical plastic shells filled with various fuel C256900100015 mixtures. Shells were nominally 15 mu-m thick with C256900100016 overcoating of 0.1 mu-m Al. Diameter of the shell was C256900100017 860 mu-m. Different target fills were used. For C256900100018 primary experiment pD fusion an equimolar mix of C256900100019 deuterium and hydrogen fill gas with 5.33 atm of each C256900100020 was used. For background measurements pure D2 at C256900100021 pressure of 8 atm and pure H2 at 16 atm were used. C256900100022 DETECTOR (SCIN) Elastically scattered neutrons from dense D or C256900100023 H was measured by time of flight technique over C256900100024 flight path of 13.4 m with advanced liquid C256900100025 scintillation detector. C256900100026 (CEREN) High energy gamma rays were detected using C256900100027 threshold Cherenkov detector. Detector consist of C256900100028 converter foil where high energy photons produce high C256900100029 energy electrons which enter radiator gas CO2 cell, C256900100030 where Cherenkov light is produced if the electron C256900100031 exceeds the local speed of light. Cherenkov light is C256900100032 relayed to a photomultiplier tube and the electrical C256900100033 signal is recorded on a high-bandwidth oscilloscope. C256900100034 The threshold depends on gas pressure. In present C256900100035 study radiator gas pressure of 400 psi was used, C256900100036 which resulted in threshold of 2.9 MeV.
