内容記述 | Local space potential fluctuations have been measured during MHD activities in a low-beta NBI heated plasma in the Compact Helical System (CHS) by the use of a heavy ion beam probe (HIBP). Two types of MHD modes with accompanying potential oscillations are observed. One appears in periodic bursts with relatively low frequency (< 40 kHz) and large amplitude (20 - 40 volts), and is localized around the q = 2 surface (average minor radius rho ~ 0.7). The other appears in continuous and coherent oscillation with higher frequency (105 - 125 kHz) and smaller amplitude (~ 5 volts). This oscillation also has spatial structure. Possible interpretation for the space potential oscillations is presented. | |||||
