From: Achieving a long-lived high-beta plasma state by energetic beam injection
The results are obtained from the three beam-driven long-pulse discharges shown in the previous figure. The solid and open symbols represent the data points before and after transition, respectively, with the arrows indicating time evolution of the discharges. The error bars represent the s.d. of the measurements.
