    Sammanfattning : Additive manufacturing (AM) is an attractive way to shorten development time, reduce product weight and allow the manufacturing of more complex products than by conventional manufacturing processes. The problem arises when the previous traditional manufacturing requirements need to be fulfilled by AM as well as the volume production capability. LÄS MER

  7. 5. Modeling of Radio Frequency Heating in JET

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

    Författare :Christos Tegkelidis; Erik Lindström; [2020]
    Nyckelord :deuterium; energy; FEMIC; fusion; ICRH; JET; radio frequency heating; tritium;

    Sammanfattning : This study examines the efficiency of ion cyclotronresonance heating in multi-ion plasmas in JET (Joint EuropeanTorus), using deuterium and tritium as fuel along with smallconcentrations of a third ion species. In particular, two ionminority scenarios, hydrogen and helium, as well as a 3-ionscenario using beryllium were constructed. LÄS MER
