  1. 1. MCNPX Simulations for Neutron Cross Section Measurements

    Author : Milan Tesinsky; Janne Wallenius; Alan Tkaczyk; KTH; []
    Keywords : MCNPX; neutron; cross section;

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

  5. 5. Assessment of Aircraft Radar Cross-Section for Detection Analysis

    Author : Björn Persson; Martin Norsell; Peter Bull; Ulf Ringertz; João Tasso de Figueiredo Borges de Sousa; Försvarshögskolan; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Försvarssystem; Military Technology; Aerospace Engineering; Flyg- och rymdteknik;

    Abstract : Hiding from and surprising an opponent are tactics that have been used in warfare throughout history. They were features that aircraft originally possessed when they were first used in military operations. However, development of military technology is an endless struggle between advances in technology and counter technology. READ MORE
