Book Synopsis Enhanced Confinement with Plasma Biasing in the MST Reversed Field Pinch by :
Book excerpt: We report an increase in particle confinement with plasma biasing in a reversed field pinch. Miniature plasma sources are used as electrodes to negatively bias the plasma at the edge (r/a[approx] 0.9). Particle content increases and H[sub[alpha]] radiation decreases upon application of bias and global particle confinement roughly doubles as a result. Measurements of plasma potential, impurity flow, and floating potential fluctuations indicate that strong flows are produced and that electrostatic fluctuations are reduced.
