1. 1. Determination of the source strength of an AmBe neutron source and design of flexible holder system for accurate measurements of ionising radiation

   L2-uppsats, Uppsala universitet/Tillämpad kärnfysik

   Författare :Mathilde Ragot; [2022]
   Nyckelord :neutron source nuclear physics;

   Sammanfattning : The goal of this project was to determine the source strength of an Americium-Beryllium neutron source by irradiating metal foils of different elements. The irradiated foils were then placed on a High Purity Germanium detector and γ-decay from the decay of the neutron induced reaction products was observed and used to deduce the neutron flux.

3. 2. Prototyping of an automated cyclic Neutron Activation Analysis setup

   Master-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

   Författare :Cornelius Maurer; [2022]
   Nyckelord :Nuclear Physics; Neutron activation analysis; cyclic-NAA; Physics and Astronomy;

   Sammanfattning : A prototype Neutron Activation Analysis (NAA) setup based on a Deuterium-Tritium (DT) neutron generator is under development at Lund University. It serves as proof-of-principle for NAA based on a Compact Accelerator-driven Neutron Source. LÄS MER

4. 3. Modeling of Low-Energy Neutron Scattering in Liquid Hydrogen Using NCrystal

   Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/European Spallation Source ESS AB; Lunds universitet/Kärnfysik

   Författare :Tim Günter; [2022]
   Nyckelord :ESS; European Spallation Source; neutron; scattering; moderator; liquid hydrogen; modeling; ncrystal; njoy; Physics and Astronomy;

   Sammanfattning : The European Spallation Source ESS, under construction in Lund, Sweden, aims to produce high-brightness and intensity neutrons for a multitude of experiments upon completion. An efficient production of neutrons requires elaborate understanding of the moderation process which slows the neutrons from relativistic speed to a kinetic energy of meV. LÄS MER

5. 4. Constructing and commissioning of a Multi-Grid neutron detector prototype for the European Spallation Source

   Master-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/European Spallation Source ESS AB

   Författare :Rebecka Wahlén; [2022]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : A prototype of a novel 10B-based neutron detector called the Multi-Grid detector has been constructed, tested and commissioned for the European Spallation Source (ESS). The detector is constructed after the specifications set by the CSPEC instrument at ESS and is therefore called the CSPEC Multi-Grid detector. LÄS MER

7. 5. Investigation on Operation of the Compact Molten Salt Reactor by Modelling the Primary Circuit in GeN-FOAM

   Master-uppsats, KTH/Fysik

   Författare :Jelle Oving; [2022]
   Nyckelord :molten salt reactor; GeN-Foam; delayed neutrons; OpenFOAM; multi-physics; smältsaltreaktor; GeN-Foam; fördröjda neutroner; OpenFOAM; multifysik;

   Sammanfattning : In recent years there has been a revision of the molten salt nuclear reactor concept for production of power. Moving of fissile material throughout the primary circuit for these types of reactors creates the necessity of novel physics solvers to study movement of delayed neutron precursors, plant operation, accident scenario's; crucial for design.
