  5. Meta-analysis of Tokamak reactor designs

    Hernández, Manuel S. (Manuel Segundo)Massachusetts Institute of Technology2016

    The long-term interest in nuclear fusion using tokamaks has yielded many published reactor designs. This study performs the first meta-analysis of tokamak reactor designs in an attempt to unveil new understanding not available in the traditional bottom-up method of looking at each design …

    Kagan, Grigory (Grigory Alexandrovich)Massachusetts Institute of Technology2009

    This thesis aims at better understanding of the tokamak pedestal, which is a defining feature of the so-called "High Confinement Mode" or "H Mode" of tokamak operation. This region is characterized by a drastic plasma density drop over a relatively short radial distance, typically of order of the …
