    2 Data Analysis Exercise of User Crossover Between Facilities Background • At the RDA Third Plenary Meeting in March , the EU pan-data project team presented a user survey of users who performed experiments both at neutron and at photon sources in Europe. SNS was invited to join the exercise during the discussion. Before the SNS, the world's spallation neutron sources operated in the hundred-kilowatt range. The SNS actually became a world-record holder in August when it reached kilowatts, earning it an entry in the Guinness Book of World Records as the world's most powerful pulsed spallation neutron source. Beam power isn't merely a numbers game. The time-of-flight technique was used with the ring scattering geometry in a laboratory with low neutron scattering background to measure the angular distributions of the cross sections for elastic and inelastic scattering of 14 MeV neutrons in natural chromium, iron, nickel, and niobium. Specifically for inelastic scattering included were: the MeV and MeV levels of {sup Author: G.F. Knoll.

Abstract. The neutron spectrum of a pulsed neutron reactor at subcritical state is different from that evaluated by k-eigenvalue mode, because of the time needed in the neutron slowing-down process from fast to thermal energy time needed in slowing down does not depend on the degree of subcriticality, but the decreasing speed of neutron flux becomes Author: Takanori Kitada, Thanh Mai Vu, Noboru Dobuchi.
