  1. 1. The Commissioning of a Pixelated Charge-particle Detector : for High-sensitivity Measurements of Hydrogen

    Kandidat-uppsats, Uppsala universitet/Tillämpad kärnfysik

    Författare :Joacim Stenlund; Aram Himelius; [2023]
    Nyckelord :;

    Sammanfattning : The Tandem Laboratory at Uppsala University, a national research infrastructure forworld-leading materials analysis, has a long history of performing hydrogen measurementusing NRA (Nuclear Reaction Analysis). This project intents to diversify the infras-tructure for hydrogen measurement by investigating the feasibility of an advanced ERCS(Elastic Recoil Coincidence Scattering) system, enabling finer detection limits.

  3. 2. Coincidence Factor and Battery Energy Storage Systems for Industrial Electrical Power Supply : A Field Study of Building 178 at Scania AB, Södertälje

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Lucas Wallhager; [2023]
    Nyckelord :Coincidence factor; Industrial electric load diversity; Velander; Normal distribution; Herman-Beta; Battery energy storage system; Sammanlagringsfaktor; Industriell elförbrukning; Velander; Herman-Beta; Batterier för energilagring;

    Sammanfattning : Coincidence factors have been researched since the late 1800s, as they displays the ratio between the maximum coincidencental power usage of a system, and the sum of the maximum individual loads of the system. Accurate estimations of the highest coincidental power usage allow for minimal material usage when constructing substations, transformers, overhead lines, and cables for power transmission. LÄS MER

  4. 3. 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

  5. 4. Is Triple Coincidence a Viable Method for Nuclear Weapons Detection in Light of Double Coincidence Methods?

    L3-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Karl Herlin; [2021]
    Nyckelord :Xenon; Coincidence; Nuclear weapons; Monte Carlo; simulation; Double coincidence; Triple cpincidence; isotope;

    Sammanfattning : A fully functioning Comprehensive nuclear-Test-Ban Treaty (CTBT) is essential for a world free of nuclear weapons. To measure radionuclides in the atmosphere in accordance with the CTBT, facilities such as SAUNA uses double coincidence techniques to discriminate between interesting Xenon isotopes. LÄS MER

  7. 5. Implementation and characterization of Silicon detectors for studies on neutron-induced nuclear reactions

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

    Författare :Leo Lehtilä; [2019]
    Nyckelord :Silicon detector; Silicon telescope; Ultra-thin silicon detector; Energy resolution; Radioactive source; Am-241; Cf-252; Fission Fragments; Alpha Particles;

    Sammanfattning : Energy resolution characteristics of silicon surface barrier detector signals amplified by different preamplifiers and spectroscopic amplifiers have been studied. The characterization has been done using alpha particles from an 241Am source and spontaneous fission fragments from two Cf sources. LÄS MER
