Impact of multifold magnetic structure on spectroscopy analysis in Heliotron J based on EMC3-EIRENE simulation
The distribution pattern of the connection length in the divertor region of Heliotron J was calculated by the field line tracing method. A multifold layer structure, characterized by the range of connection length, was revealed to interpret the response of the transport of the lower-charged impurity ions to the divertor structure. Impurity transport simulated by the EMC3-EIRENE code shows that lower-charged impurity ions tend to concentrate in the first multifold layer. This result is consistent with the line-integral extreme ultraviolet spectroscopy measurement, which implies that the impurity's response to the divertor topological structure needs to be considered in interpreting the spectroscopy result.
