  1. 1. Calibration of RPWI Langmuir Probe Data

    Kandidat-uppsats, Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

    Författare :Gurpreet Kaur; [2023]
    Nyckelord :RPWI;

    Sammanfattning : In this report calibration of the four probes attached onto the JUICE spacecraft has been made.The JUICE spacecraft (JUpiter Icy Moon Explorer) is a spacecraft which will investigate theenvironment on and around Jupiter and its four biggest moons. LÄS MER

  3. 2. Estimating Charging on a Sounding Rocket Experiment Using Plasma Simulation

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

    Författare :Emelie Modin; [2020]
    Nyckelord :Current Voltage Characteristics; SoundingRocket; SPIDER-1; SPIDER-2; Aurora; SPIS;

    Sammanfattning : The aim of this project is to model current volt-age characteristic curves for different plasma conditions (i.eelectron density, electron temperature, ion temperature andplasma potential) that can be found in active auroras. This isdone by simulating the charging of a FFU with a connectedLangmuir probe in the software SPIS. LÄS MER

  4. 3. Plasma density characteristics of magnetic holes near the Kronian magnetosphere boundary surfaces

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

    Författare :Marlon Luis Bause; [2020]
    Nyckelord :Magnetic holes; Saturn; Langmuir Probe; plasma electron density; Magnetosphere;

    Sammanfattning : Localized structures of the magnetic field strength depression are often observed in the interplanetarymedium, and they are called ‘magnetic holes’ after the original work of Turner et al. 1977. A numberof observations of similar features have been reported, while the mechanisms of their origin have notfully understood yet. LÄS MER

  5. 4. Searching for Titan's tail

    Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

    Författare :Joakim Kvarnström; [2018]
    Nyckelord :Titan; Ionosphere;

    Sammanfattning : We have used Cassini measurements of electron density from Saturn's magnetosphere to search for a plasma tail behind the moon Titan. Such a plasma tail would consist of plasma that manage to escape Titan's gravitational pull and leave Titan's ionosphere to contribute to the plasma distribution in the Saturn system. LÄS MER

  7. 5. Electron cooling in a cometary coma

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

    Författare :Simon Alinder; [2017]
    Nyckelord :Comet; Plasma; Inner coma;

    Sammanfattning : The ESA Rosetta spacecraft investigated comet 67P/Churyumov-Gerasimenko duringtwo years from August 2014 to the end of September 2016. The dual Langmuir probewas used to measure plasma parameters including the thermal energy of theelectrons. LÄS MER
