  1. 1. Simulations of a back scatter time of flight neutron spectrometer for the purpose of concept testing at the NESSA facility.

    Master-uppsats, Uppsala universitet/Tillämpad kärnfysik

    Författare :Benjamin Eriksson; [2018]
    Nyckelord :fusion; JET; Geant4; NESSA; NESSA facility; back scatter tof; tof; time of flight; spectrometer; neutron; ITER; Monte Carlo; simulation;

    Sammanfattning : A back scatter time of flight neutron spectrometer consisting of two scintillation detectors is simulated in Geant4 to examine whether it is possible to perform a proof of concept test at the NESSA facility at Uppsala University. An efficiency of ε = 2.45 · 10^-6 is shown to be large enough for a neutron generator intensity of 1. LÄS MER

  2. 2. Monte Carlo modelling of an X-ray fluorescence detection system by the MCNP code

    Master-uppsats, Mittuniversitetet/Avdelningen för elektronikkonstruktion

    Författare :Xiaolei Xia; [2018]
    Nyckelord :MCNP; Monte Carlo modelling; XRF detection system;

    Sammanfattning : This survey has shown, using the Monte Carlo N-Particle(MCNP) code to model a detection system, to demonstrate that it is possible to design a system to measure hazard elements in polluted water. At first, the measurement method needs to be determined. LÄS MER

  3. 3. Simulation of neutron generator assisted gamma emission tomography for inspection of fissile content in spent nuclear fuel

    Magister-uppsats, Uppsala universitet/Tillämpad kärnfysik

    Författare :Erik Wickman; [2017]
    Nyckelord :;

    Sammanfattning : This is a feasibility study of a new measurement technique for spent nuclear fuel. The technique combines gamma emission tomography with neutron activation analysis. The idea is to measure high-energy characteristic gamma from short-lived fission products and thereby verify the fissile material content in spent nuclear fuel assemblies. LÄS MER

  4. 4. Mapping, Analysis and Protection of Electronic Circuits Against Radiation in the Accelerator Tunnel of the ESS

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Johannes Hedberg Kazantzidis; [2015]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Estimation of radiation damage to electronics is complex and requires knowledge of several disciplines. Such estimation is important in the assessment of design and construction of systems in radiatory applications. LÄS MER

  5. 5. MCNP-modell för beräkning av neutrondos och DPA på reaktortanken vid Ringhals 2

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad kärnfysik

    Författare :Erik Dalborg; [2013]
    Nyckelord :MCNP; DPA; strålningsskador;

    Sammanfattning : In this report an MCNP (Monte Carlo N-Particle) model is described for the reactor vessel at Ringhals 2. The model is validated against the specific activity in neutron dosimeters, extracted in 1977, 1984 and 1994. LÄS MER
