  1. 11. Development and Characterization of Parallel-Plate Avalanche Counters for Nuclear Physics Experiments

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Matthias Carlsson; [2018]
    Keywords : PPAC; Parallel-Plate Avalanche Counters; Gas Ionizing Detector; Gas Amplification; Characterization; NFS; Radioactive source; Am-241; Cf-252; Fission Fragments; Alpha Particles; Time Resolution; Angular Dependence; Gas Pressure Dependence; Townsend Coefficient; PPAC Design; Manufacture; Manufacturing; Mylar foil; Aluminium Evaporation;

    Abstract : Parallel-plate avalanche counters, PPACs, are commonly used to detect fission fragments. The PPAC detects them and mark (very accurately) the time of detection. Such measurements can be used to measure the neutron energy (via time-of-flight) to study neutron-induced fission. READ MORE

  3. 12. Virtual Studies of Nuclear Fission : A comparison of n- and p- induced fission using GEF

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Dany Gabro; [2017]
    Keywords : Fission; proton induced; neutron induced; GEF; uranium; neptunium; thorium; protaktinium;

    Abstract : A General Description of Fission Observables (GEF) version 2016/1.2 is a software which simulates various types of fission. The main objective of this project is to compare the proton induced fission with the neutron induced fission of the same fissioning system. The proton induced fission was recently introduced to GEF and is relatively untested. READ MORE

  4. 13. Neutron Irradiation of Concrete at TSL : a Comparison of Nuclide Specific Measurmentswith FLUKA Simulations.

    University essay from Uppsala universitet/The Svedberg-laboratoriet

    Author : Christer Åström; [2017]
    Keywords : Neutron; Irradiation; Concrete; FLUKA; The Svedberg Laboratoy; Monte Carlo; Gamma-ray Spectroscopy;

    Abstract : This thesis studies the possibility of using the Monte Carlo simulation program FLUKA to determine the neutron induced radioactivity of concrete walls at the The Svedberg Laboratory (TSL) in Uppsala. If a simulation of the activation would produce reliable results, it would be a useful complement to measurements for the decommissioning and clearance of the buildings of the facility. READ MORE

  5. 14. Detection of uranium fission products through neutron activation

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : August Barot; Mikael Andersson; [2016]
    Keywords : ;

    Abstract : Abstract—Uranium compounds are used in many nuclear power plants, and the neutron-induced fission reactions produce many decay products. Some of these are of interest from an efficiency or safety point of view. For this reason, it is important to quantitatively and qualitatively know these nuclides. READ MORE

  6. 15. Microgels at ultrahigh densities : a small angle neutron scattering study

    University essay from Lunds universitet/Kemiska institutionen

    Author : Sofi Nöjd; [2012]
    Keywords : Fysikalisk kemi; Chemistry;

    Abstract : Populärvetenskaplig sammanfattning Microgelpartiklar är runda partiklar som har förmågan att ändra storlek beroende på olika yttre påverkan. I detta projekt har vi tittat på partiklar som blir upp till 10 gånger mindre när temperaturen höjs från 15˚C till 39˚C. READ MORE
