Popis: | NORTH is a small-sized tokamak located at the Technical University of Denmark. It can be operated both as a spherical tokamak and a simple magnetized torus (SMT). Here we show first experimental results. We discuss the setup of the device, including the layout of the vacuum vessel, the magnetic field coils, the power supply systems, the heating sources, diagnostics, and the control system. We present measurements in discharges that have been heated by electron cyclotron resonance heating at the fundamental resonance. The waves have been injected both from the low-field side and the high-field side, and rich fluctuation spectra in Langmuir probe and Rogowski coil signals are presented during the different plasma phases. Finally, we discuss research plans and further installations to be made on NORTH. |
