  1. 1. Hollow Cathode Deposition of Thin Films

    Författare :Lars-Erik Gustavsson; Ladislav Bárdoš; Hana Baránková; Claes Nender; Uppsala universitet; []
    Nyckelord :Electronics; Hollow cathode; Hybrid plasma; PVD; TiN films; Ferromagnetic substrates; Magnetized plasma; CrN films; Elektronik;

    Sammanfattning : Thin films of metals and compounds have a very wide range of applications today. Many of the deposition methods used for the production of such films utilize plasma to support the growth the film, e.g. by the supply of energy and the enhancement of reactivity. LÄS MER

  3. 2. Coil Design and Related Studies for the Fusion-Fission Reactor Concept SFLM Hybrid

    Författare :Anders Hagnestål; Olov Ågren; Vladimir Moiseenko; Ladislav Bardos; Jan Scheffel; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fusion; Fission; Hybrid reactor; Actinides; Mirror Machine; Quadrupolar mirror; Coils; Fysik; Physics;

    Sammanfattning : A fusion-fission (hybrid) reactor is a combination of a fusion device and a subcritical fission reactor, where the fusion device acts as a neutron source and the power is mainly produced in the fission core. Hybrid reactors may be suitable for transmutation of transuranic isotopes in the spent nuclear fuel, due to the safety margin on criticality imposed by the subcritical fission core. LÄS MER
