Description
Plasma disruption which is a kind of abrupt nonlinear instability phenomenon often occurs in the plasma discharges.; i.e.plasma disrupts within very short time and then is terminated.
When disruption occurs, the plasma current will burn out very quickly, and at the same time poloidal field coil current will be released in fault discharging mode. And that will generate strong coupling interference on the weak signal of quench causing false trigger of detecting system.
With the development of experiments and operation parameters increasing constantly, it is urgently needed to estimate the residual induction noise on detection signals under extreme discharge conditions which help to confirm the reasonable range of detection compensation coefficients and optimize the threshold values for detection ,avoiding reoccurrence of false triggers caused by thess events.
