However, the concept of vertically elongated plasma cross-section, with benefits to the energy confinement time, led to vertical instabilities. To overcome this problem, complex closed feedback loop control systems with a vertical position measurement, signal processing, control algorithm, power supplies and active actuating coils are used.Feedback controlmagnetic diagnosticstokamaksFeedback StabilizationPosition ControlControl-SystemTokamaktext::journal::journal article::research article
