  1. 1. MCNPX Simulations for Neutron Cross Section Measurements

    Författare :Milan Tesinsky; Janne Wallenius; Alan Tkaczyk; KTH; []
    Nyckelord :MCNPX; neutron; cross section;

    Sammanfattning : This thesis presents MCNPX simulations of the SCANDAL set-up used at the Theodor Svedberg Laboratory for neutron scattering cross-section measurements. The thesis describes processes and data important for the upcoming off-line data analysis. LÄS MER

  2. 2. The neutron-induced fission cross section of 233Pa : and the quest for clean and safe nuclear energy

    Författare :Fredrik Tovesson; Andreas Oberstedt; Dietrich Hilscher; Örebro universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Fysik; fission; cross section; Pa-233; U-233; fysik; Physics; Fysik; Fysik; Physics;

    Sammanfattning : Neutron-induced fission of 233Pa has been investigated between 1.0 and 8.5 MeV, and the reaction cross section was determined. Due to the short half-life of 233Pa for β-decay, fission events from the daughter product 233U affect the analysis of the protactinium experiment. LÄS MER
