  1. 11. Development of a Neutron Activation Analysis station at the Lund Ion Beam Analysis Facility

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Josephine Lindsey-Clark; [2021]
    Keywords : Neutron Activation Analysis; NAA; European Spallation Source; ESS; Lund Ion Beam Analysis Facility; LIBAF; Gamma-Ray Spectra; Physics and Astronomy;

    Abstract : This report outlines the first stages of the development of the Neutron Activation Analysis station at the Lund Ion Beam Analysis Facility in the Division of Nuclear Physics, Lund University. The motivation for this project is to use the Neutron Activation Analysis detection technique for environmental monitoring around the European Spallation Source, soon to come into operation.

  3. 12. Investigating RT using two-particle angular correlations in proton-proton collisions

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Dilan Chroscik; [2020]
    Keywords : particle physics; proton-proton collisions; two-particle angular correlations; underlying event; relative transverse activity; ALICE; LHC; collective flow; long range correlations; Physics and Astronomy;

    Abstract : The observable, RT , is investigated using two-dimensional (∆η, ∆φ) angular correlations, where ∆η and ∆φ are the differences in pseudorapidity and azimuthal angle respectively, between the trigger and associated tracks. The analysed data consists of reconstructed tracks, from proton-proton collisions at collision energy ps = 13 TeV, taken from the ALICE detector at the LHC. READ MORE

  4. 13. A Numerical Calculation Tool Design for the Performance Assessment of a Bench-Scale Thermochemical Heat Storage System

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : DIYUE WANG; [2020]
    Keywords : Calculation tool; SrCl2-NH3; Performance evaluation; Mass; Energy; Beräkningsverktyg; SrCl2-NH3; Prestandasutvärdering; massa; energi;

    Abstract : Thermochemical heat storage (TCS) is a technology to convert the heat and cold energy into chemical energy, via reversible chemical reactions, to be stored for heating and cooling applications. TCS technology is gaining interest for its very compact energy storage densities offering attractive thermal energy storage (TES) alternatives to decrease energy-related greenhouse gas(GHG) emissions and contribute to sustainable development.

  5. 14. Accurate Abundances of Giant Stars in the Local disk: A manual analysis of IR APOGEE spectra

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Ivalu Barlach Christensen; [2020]
    Keywords : Galactic Chemical Evolution; Astrophysics; Astronomy; IR Spectroscopy; Milky Way; Abundance; Physics and Astronomy;

    Abstract : Purpose: In order to study the Galactic Chemical Evolution, elemental abundances are needed. The purpose of this work is to investigate the chemical evolution of the Milky Way by determining several elemental abundances of giants in the local disk. READ MORE

  6. 15. Mapping DFT to effective Hamiltonians

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Paul André; [2019]
    Keywords : DFT; Hamiltonians; Nuclear; Physics; Structure; Technology and Engineering;

    Abstract : This thesis proposes a new effective Hamiltonian to represent the interactions taking place in the atomic nucleus. This estimated Hamiltonian is analogous to the Pairing-Plus-Quadrupole model and this work is focused exclusively on the quadrupole part, with the aim of describing nuclear structure in a computationally efficient way.
