Nanocrystalline vanadium dioxide (VO 2 ) thin films were grown on glass substrates by using reactive direct current magnetron sputtering and in situ thermal treatments at low preparation temperatures (≤350°C). The VO 2 thin films were characterized by grazing-incidence X-ray diffraction, field emission scanning electron microscope, transmission electron microscopy and spectroscopic...
Summary form only given. Lead activation system is used to measure very low yield (above 106) of DT reaction, and it can also be applied to measure DD reaction neutrons (2.45 MeV). These neutrons produce 207mPb radioactive nuclide by the reaction 208 Pb(n,2n)207mPb and 207Pb(n,n)207mPb in Pb sheath that surrounds a NaI(Tl) detector or 1.5 cm thick Pb disks in front of NaI(Tl) detector. Using this...
Summary form only given. The ICF experiments performed at Shenguang II facility need to measure the total energy of stimulated Raman scattering (SRS) and stimulated Brillouin scattering (SBS) as well as the weak backscattered SRS and SBS. Generally used laser calorimeter whose sensitivities are rather low, cannot meet the needs of such measurements. Because of long signal cable and AC power disturbance,...
