Disney World should have gone nuclear
There is extra significance to the American Nuclear Society holding its annual meeting in Orlando, Florida, this past week. That’s because in 1967, the state of Florida passed a law allowing Disney World to build a nuclear power plant.

An improved confinement has been observed on HT-6M tokamak after application of Edge Ohmic Heating (EOH) which makes plasma current rapidly ramp up from an initial steady state (Ip=55 kA) within a small time scale (0.4 ms) to a second steady state (Ip=60 kA) with a ramp rate of 12 MA/sec. The improved confinement is characterized by (a) increased average density ne; (b) reduced Hα radiation; (c) reduced density fluctuations both in the center and at the edge; (d) a steeper ne and Te profile at the edge; (e) the changed profiles of plasma parameters ne(r), q(r) and j(r); (f) transferred the oscillation modes of the soft-X ray signals from Mirnov fluctuation (12 kHz) to sawtooth oscillation (1.7 kHz). The changes of edge fluctuation, radial electric field and bremsstrahlung during EOH were measured and discussed in details. The measured values of βp+1i/2 and soft-X ray sawtooth inversion radius implied the anomalous current penetration.
