2007 (English)In: Japanese Journal of Applied Physics, ISSN 0021-4922, E-ISSN 1347-4065, Vol. 46, no 10A, 6831-6833 p.Article in journal (Refereed) Published
Fast magnetic fluctuation (0) levels are measured using a newly developed complex edge probe (CEP) in the edge region of TPE-RX reversed-field pinch plasma. The CEP is installed inside a vacuum vessel and is sensitive to fast delta B. The delta B levels measured using the CEP are compared with those measured using an extensive magnetic measurement system (MMS), which is located outside the vacuum vessel and has little sensitivity to fast delta B. The delta B levels before and after the appearance of the locked mode (LM) are compared in both the CEP and MMS signals. It was found that the rapid increase in the delta B signal level obtained using the MMS just after the appearance of LM is mainly caused by the slowing of plasma rotation.
