Abstract
Strong magnetohydrodynamic activity has been observed in PDX neutral-beam-heated discharges. It occurs for βTq>~0.045 and is associated with a significant loss of fast ions and a drop in neutron emission. As much as 20%-40% of the beam heating power may be lost. The instability occurs in repetitive bursts of oscillations of ≤ 1 msec duration at 1-6-msec intervals. The magnetohydrodynamic activity has been dubbed the "fishbone instability" from its characteristic signature on the Mirnov coils.Received 29 September 1982DOI:https://doi.org/10.1103/PhysRevLett.50.891©1983 American Physical Society
