Stability of Tokamak and Rfp Plasmas with an Extended Region of Low Magnetic Shear


It has been observed experimentally that magnetically confined plasmas, characterised by the safety factor q with a small or slightly inverted magnetic shear, have good confinement properties. Such plasmas typically have no internal transport barrier, operate with q95 ∼ 4 and are good candidates for long pulse operation at high fusion yield in the reactor… (More)
