In magnetic confinement plasmas, plasma rotation plays an important role in the penetration and propagation processes of external RMP fields. To investigate the relation between the penetration of RMP fields and plasma flow, we have created a new type of Mach probe array to measure plasma flow profiles. The experimental results show that plasma flow around the q = 3 resonant surface decreases with increases in RMP fields.
