Conclusion

​

From our statistics and analysis, we can safely concluded that the best environment for generating MHD instabilities during a period of discharge is one with high plasma current and low magnetic field relative to stable discharges. This would result in a low safety factor and large power spectrum with a minimal number of prominent peaks. From the significance statistics gathered in this research, it is speculated that the plasma current correlates with an environment suitable for generation of MHD structures but not their actual presence. It should be noted that an optimal magnetic field value for a given plasma current strength exists for MHD generation. Future research warrants investigation concerning this value’s relationship to plasma current strength. It is also suggested t-testing be performed on signals from different Mirnov coils to statistically confirm the amplitude differences seen on these coils is solely related to distance, and not another factor.


The discovered correlations and relationships found in this experimentation can contribute to determining with finality the cause of MHD activity and assist in allowing for the reproduction of MHD instabilities in a controlled environment for study.
