A new magnetic coil system consisting of two helical arrays of triple magnetic coils has been recently installed inside the TJ-II vacuum vessel <ref>Measurements of magnetic fluctuations in TJ-II plasmas with new in-vessel helical arrays of magnetic coils (in preparation; to be sent to Review Scientific Instruments)</ref>. It covers densely sector D of the device. | |||
This proposal requests machine time with NBI plasmas in order to detect NBI-driven Alfvén modes, measure phase differences and figure out the corresponding toroidal mode numbers. | This proposal requests machine time with NBI plasmas in order to detect NBI-driven Alfvén modes, measure phase differences and figure out the corresponding toroidal mode numbers. | ||
