  1. 1. Implementing Total Electron Content in the Grand Unifed Incoherent Scattering Design and Analysis Program for Investigation of Causes to Scintillations

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Samuel Sonesson; [2023]
    Keywords : Total Electron Content; Scintillation; Incoherent Scattering; Ionosphere;

    Abstract : Functionality for calculating and plotting diferent Total Electron Content (TEC) measurements such as Slant Total Electron Content (sTEC), error in sTEC, and VerticalTotal Electron Content (vTEC) was implemented into the data analysis program fromEuropean Incoherent Scattering Scientifc Association (EISCAT), the Grand Unifed Incoherent Scattering Design and Analysis Program (GUISDAP). This utilises a thin-singlelayer model of the ionosphere to convert sTEC into the more analytically useful vTEC. READ MORE

  3. 2. Incoherent Scattering of Twisted Radar Beams from the Ionosphere

    University essay from Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

    Author : Viktor Lannér; [2017]
    Keywords : ionosphere; plasma; twisted beams; orbital angular momentum; oam effects;

    Abstract : In the search for natural orbital angular momentum (OAM) effects, some of the first incoherent scatter experiments with twisted radar beams during aurora were conducted at Poker Flat Incoherent Scatter Radar (PFISR), Alaska, USA, in October 2012. Experimental data of scatter from beam configurations with opposite twists were investigated. READ MORE

  4. 3. A Probabilistic Model of Neutron Scattering in Thin Films

    University essay from Lunds universitet/Matematisk statistik

    Author : Hanna Wu; [2013]
    Keywords : Mathematics and Statistics;

    Abstract : In the light of a world-wide shortage of helium-3 (3He) a development of novel neutron detector systems (NDS) is necessary. This requires mathematical descriptions of the neutron scattering process in thin films. READ MORE

  5. 4. Incoherent scattering in the ionosphere from twisted radar beams

    University essay from Institutet för rymdfysik, Uppsalaavdelningen

    Author : Fredrik Waldemarsson; [2011]
    Keywords : OAM; orbital angular momentum; twisted radar beams; incoherent scattering;

    Abstract : Twenty-odd years ago, scientists managed to produce several new techniques for manipulating certain properties of laser and microwave radiation. These new properties made it possible for the radiation to contain a lot more information than what was previously known. READ MORE
