A survey is made of experiments in different versions of the Nagoya Bumpy Torus (NBT). Hot-electron-plasmas with β-values up to 5% were routinely produced by electron-cyclotron heating. Plasma confinement studies of the toroidal plasma have revealed that the confinement times fall short of neoclassical predictions, but global stability can be achieved. A density of 1013cm−3 and an ion temperature of 100 eV have been obtained simultaneously on NBT-1M by the use of hot-electron rings in combination with ICRF heating. The electrons are still in the collisional regime.
