متن کاملGeneration and confinement of hot ions and electrons in a reversed-field pinch plasma
By manipulating magnetic reconnection in Madison Symmetric Torus (MST) discharges, we have generated and confined for the first time a reversedfield pinch (RFP) plasma with an ion temperature >1 keV and an electron temperature of 2 keV. This is achieved at a toroidal plasma current of about 0.5 MA, approaching MST’s present maximum. The manipulation begins with intensification of discrete magne...
متن کاملObservation of energetic electron confinement in a largely stochastic reversed-field pinch plasma
Runaway electrons with energies 100 keV are observed with the appearance of an m=1 magnetic island in the core of otherwise stochastic Madison Symmetric Torus Dexter et al., Fusion Technol. 19, 131 1991 reversed-field-pinch plasmas. The island is associated with the innermost resonant tearing mode, which is usually the largest in the m=1 spectrum. The island appears over a range of mode spectra...
متن کاملOn the Physics of Improved Confinement During Pulsed Poloidal Current Drive in MST Reversed-Field Pinch
Reduction of core-resonant magnetic fluctuations and improved confinement in the Madison Symmetric Torus reversed-field pinch (MST RFP) have been routinely achieved by applying the surface poloidal electric field. The created inductive poloidal electric field drives current in plasma which leads to the improved confinement. To study the effect we developed a relatively simple 1-D model in cylin...
متن کاملHeavy ion beam probe operation in time varying equilibria of improved confinement reversed field pinch discharges.
Operation of a heavy ion beam probe (HIBP) on a reversed field pinch is unique from other toroidal applications because the magnetic field is more temporal and largely produced by plasma current. Improved confinement, produced through the transient application of a poloidal electric field which leads to a reduction of dynamo activity, exhibits gradual changes in equilibrium plasma quantities. A...
