  1. 41. Characterization of γ-rays at MAST

    Kandidat-uppsats, Uppsala universitet/Tillämpad kärnfysik

    Författare :Erik Blom; [2019]
    Nyckelord :fusion; MAST; MAST upgrade; neutron collimated flux monitor; neutron camera; gamma-ray;

    Sammanfattning : The γ-ray characterizing possibility of the neutron collimated flux monitor (in short, Neutron Camera) at the Mega Ampere Spherical Tokamak (MAST) is explored. Typically used to monitor neutron emission, the Neutron Camera has excellent neutron/γ-ray discrimination properties and thus presents the opportunity to measure spatially and temporally resolved γ-ray emission - a possibility of an additional fusion diagnostics method with already existing equipment.

  3. 42. Development of Spectroscopic Measurements for Raman and Thomson Scattering Diagnostics ——Applications in Combustion and Plasma

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

    Författare :Miaoxin Gong; [2019]
    Nyckelord :Raman scattering; Raman spectroscopy; Thomson scattering; stray light suppression; periodic shadowing; high dynamic range imaging; digital micro-mirror device; DMD; laminar flames; combustion; gas discharge; plasma; laser diagnostics; spectrometer; improved spectroscopy; spectroscopy; Physics and Astronomy;

    Sammanfattning : This thesis work concerns methods for improved spectroscopy including stray-light suppression, dynamic range improvement and signal enhancement. These methods were applied in Raman and Thomson- scattering spectroscopy in combustion and plasma. LÄS MER

  4. 43. Ion Cyclotron Resonance Heating in WEST

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

    Författare :Elvis Rodas; [2019]
    Nyckelord :tokamak; WEST; ICRH; FEMIC.;

    Sammanfattning : In a fusion power plant the plasma must be confined to prevent instabilities and energy loss. The confinement machine studied is a tokamak. The focus of the project is to optimize ion resonance heating in WEST. LÄS MER

  5. 44. Farmakokinetiska egenskaper hos dexmedetomidin som CRI under generell anestesi på häst

    Kandidat-uppsats, SLU/Dept. of Clinical Sciences

    Författare :Caroline Abrahamsson; Sandra Johansson; [2019]
    Nyckelord :dexmedetomidin; CRI; bolus; anestesi; häst; farmakokinetik; hjärtfrekvens; blodtryck;

    Sammanfattning : Det här är en prospektiv, experimentell studie med syfte att undersöka dexmedetomidins farmakokinetiska egenskaper. Studien gjordes på sex hästar som genomgick generell anestesi och fick constant rate infusion (CRI) med dexmedetomidin. Studien gjordes vid Sveriges lantbruksuniversitet (SLU) Campus Ultuna i Uppsala under vintern 2018. LÄS MER

  7. 45. Reconstructing ICMEs with the toroidal Grad-Shafranov method

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

    Författare :Moa Skan; [2019]
    Nyckelord :space physics; plasma; coronal mass ejections; interplanetary coronal mass ejections;

    Sammanfattning : The main objective of this thesis is to model the magneticstructure of interplanetary coronal mass ejections (ICME) measuredin-situ from the WIND spacecraft positioned at L1. The modeling isdone by a magnetohydrodynamic reconstruction technique based onthe GS equation with a toroidal geometry. LÄS MER
